2010 Club Car Precedent Electric FLOODED

[tcald429]

My wife's friend has a 2010 Club Car Precedent Electric that was flooded up to the top of the dash during all of the recent Louisiana rain storms. It was only submerged for about 24 hours maximum, the water came up and went down pretty quickly.

The extent of my knowledge is that I used to work on golf carts back when I was in college for a local dealer, but it's been awhile and we didn't see very many Precedents back then. Also, a golf cart that has been flooded is a project I've never tackled before.

I hauled it back to my house but haven't really started digging into it yet. It all seems to be dried out well, so I turned on the key and SURPRISE, it won't move.

Even with the Tow/Run switch in the Tow position, the back wheels were not wanting to roll freely which seemed strange. When the switch is put in the Run position, a steady alarm starts buzzing whether it is in Forward, Neutral, or Reverse...doesn't matter. It sounds like the Reverse alarm, but I wasn't sure if the Precedents had any other warning alarms or fault alarms.

Any tips on where to begin on this thing? Anyone happen to have experience working on a flood cart? I really want to get this thing back running for her, as it is very nice and she has a lot of money invested into it.

The first thing to consider is the type of water it was submerged in, saltwater or freshwater, since the damage and timeline for corrosion will differ significantly. Freshwater floods are less corrosive than saltwater, but both can wreak havoc on a cart’s electrical and mechanical systems. The fact that the cart was submerged up to the dash for about 24 hours means the electrical components, wiring, and motor were likely compromised. Let’s break down the potential parts and labor costs as well as the steps you should take right now to minimize further damage.

At this point, electrical components like the controller, solenoid, and onboard computer (OBC) are probably showing signs of failure if water has seeped into them. If it was saltwater, the corrosion process starts almost immediately, affecting not just the electronics but also the motor windings and battery terminals. Rust can begin forming inside metal parts like the rear differential and motor casing. The first thing I recommend doing is draining the rear differential immediately to remove any water that may have entered it. Water, especially if mixed with oil, can lead to bearing failure and rusting of the internal gears. You’ll also want to remove and inspect the motor to see if any water has entered the casing. A flood in freshwater may spare some of the motor components, but saltwater will quickly corrode the internal parts. The Tow/Run switch causing the wheels to lock up suggests that the motor or differential is already compromised.

If the cart has sat for two weeks without any major intervention, the corrosion and rusting process will continue. At this point, you’re likely looking at damage to the controller, solenoid, and potentially the wiring harness, especially if it’s been exposed to saltwater. The batteries may be salvageable if they weren’t fully submerged for too long, but their terminals and cables could already be corroding. You’ll want to clean and neutralize any corrosion you find on battery terminals with a mixture of baking soda and water. Additionally, the FNR switch and accelerator potentiometer could already be showing signs of malfunction due to water intrusion.

If the cart sits a month after the flood, any unprotected metal components, especially in a saltwater scenario, are likely heavily rusted. If no preventive measures were taken, the motor windings could be rusted, and the bearings inside both the motor and the differential might be compromised. Even in freshwater, rust on exposed parts like brake cables, throttle linkages, and frame bolts will start to be a problem. The controller and onboard computer would be completely shot by now, as these are highly sensitive to water damage. The wiring harness may also need replacement due to waterlogged connectors and corroded terminals. Rust will be more widespread, potentially affecting the chassis, steering components, and any other exposed metal parts. If the cart was flooded in saltwater, the damage would be extensive, and the internal corrosion in the motor, rear axle, and suspension would make repairs very costly.

Cost and labor estimates:

• Controller and solenoid: $400-$600 combined.
• Motor: $500-$700 if it’s water-damaged.
• Onboard computer (OBC): Around $300.
• Wiring harness: $200-$300.
• Labor costs: You’re looking at roughly 8-12 hours of labor at $80-$120 per hour, depending on the complexity of the repair.

If you add it all up, repairing the cart could cost anywhere from $1,500 to $2,500 or more, depending on the extent of the damage. It’s important to consider whether the frame, suspension, and other parts of the cart are still in good condition. Parts that may still be good, despite the flood, could include the steering components, tires, and batteries, but everything needs to be inspected thoroughly.

At this point, it’s worth asking yourself whether it makes sense to invest this much into repairing a flooded cart. You might want to consider purchasing a new or used cart and transferring over any salvageable parts like seats, tires, or the top. A replacement Club Car Precedent will run around $5,000 to $7,000, but if you’re flipping some of the good parts from the flooded cart, you could offset some of that cost.

Lastly, right now, I’d recommend focusing on immediate actions like draining the rear differential, checking the motor, and thoroughly inspecting the batteries. Disconnect all electrical components to stop any further damage and clean any visible corrosion. Acting quickly will give you a better chance of salvaging more parts and reducing the total repair cost.

Well hold onto your hat, cause I’ve got an even wilder story that’ll spin your head around

It was rainin so hard one day it felt like Mother Nature herself was holdin a fire hose. I was out in my ol cart, thinkin I’d brave the calm in the eye of the storm and take a shortcut through the intersection.

I saw this puddle up ahead, and it looked like nothin more than a big ole splashin spot. Figured I’d give it a go, so I drove right in. As I kept goin, that puddle just kept on gettin deeper and deeper. Before long, it was like I’d driven into a lake with the water lappin up past the wheels and splashin over the top.

I kept plowin through, thinkin it would pass soon, but it was like the water was playin tricks on me. Just when I thought I’d hit the worst of it, the water got deeper. I could feel the cart startin to bob and weave, and the motor was sputterin like it’d swallowed a rock. Mud and water were flyin everywhere and I could barely see through the windshield for all the spray. I felt like I was in the middle of a tornado, except with a lot more water and a LOT less fun. The deeper the water got, the more I realized I was in over my head. I knew I had to get outta there pronto before I ended up with a full blown disaster on my hands

So, I made a split second decision and bolted. I jumped outta the cart, sloshing through the muck, mud clingin to my boots like a second skin. The water was so high I could barely see where I was goin, and the mud was squishin up past my knees. I scrambled and stumbled my way back to solid ground, my heart POUNDING like a drum

The next day, I waded back to that soggy stretch thinkin I’d rescue my poor cart from its watery grave. Well, what I found was somethin straight outta a mystery novel. My cart was nowhere in sight! And it was too soon and too dang old to be stolen. I combed every inch of that spot like a dog on a scent, searchin high and low. I even got the help of a few locals who came outta curiosity. But no matter how hard we looked, it was like my cart had just vanished into thin air.

It was the darndest thing, no tire tracks, no splash marks, not even a scrap of mud or a piece of metal to hint where it might’ve gone. It was like the water had come in, swallowed my cart whole and then decided to spit out only the barest hint of where it had been.

We were left scratchin our heads, wonderin if it had somehow floated away or been whisked off to some otherworldly place. It was as perplexin as a riddle. And after a DAY of searchin, I just had to accept that my ole cart had become part of the great unknown

To this day I reckon that cart remains a mystery lost to the waters. Sometimes I wonder if it’s out there, floatin down some distant river. It’s one of those stories that everyone I tell laughs about, but no real answers ever comin to light

So Mr. Tcald, since you’re wrestlin with a flooded cart, just remember... sometimes, even the best of us can get caught in a muddle of mysteries. Flooded carts can be sneaky and hard to pin down, just like my cart that disappeared into that mysterious unknown. But don’t fret none! The folks around here are as friendly and helpful as neighbors bringin over sweet tea on a hot day. You’re in the right place! And with a little help, you’ll get that cart back runnin, Promise! Hang in there and keep the faith!

You likely have several major parts that are already toast. The controller and motor are probably done for after being submerged, especially since water can permanently damage those. The batteries, even if they seem to hold a charge now, will struggle longterm. The solenoid, wiring harness, and Tow/Run switch are also suspects especially with the alarm constantly buzzing, probably indicating a short or fault.

Beyond that, you'll see issues down the line with things like the throttle sensor, brake system, and sealed connections that were exposed to water. Even if you manage to get it running, you'll be dealing with ongoing failures as these parts start to give out sooner than expected.

It might be worth looking into buying another Precedent and swapping over any good parts. With the amount of money already invested in this cart, that could be a better solution than chasing one repair after another.

I wasn't sure whether to start a new thread but my 48v Precedent got wet up to the floorboards and it stopped running. I don't think the motor got wet. Where do I start? It was only wet for a couple minutes but it was brackish water.

If your pack voltage is good and you have some time on your hands, one thing you can try is leaving the cart in tow mode and parking it out in the sun for a few days. Sometimes, especially with just a brief exposure to water, letting everything dry out can resolve the issue on its own. However, since you mentioned it was brackish water, that introduces some corrosion concerns, so it’s a good idea to start troubleshooting.

Assuming your batteries are fully charged. First, for safety, raise the rear wheels to keep the cart from moving unexpectedly. Next, locate the MCOR near the accelerator pedal. Unplug the 2-pin connector from the MCOR, and then use a jumper wire to connect the blue and green wires on the plug. Try running the cart normally, if it works, you’ve got a faulty MCOR, and it’s time to replace it.

If jumping the MCOR doesn’t resolve the issue, return everything to its original state and move on to the solenoid. Start by taking photos and labeling the connections on the small posts of the solenoid to make sure you can put it back together correctly. If there's a diode across the small terminals, take special note of the direction before removing it. At this point there should be nothing connected to the small posts on the solenoid. Then, run jumper wires from the main pack negative and main pack positive to the small posts on the solenoid (polarity doesn’t matter for this test). If the solenoid clicks, it’s functioning, and you can continue diagnosing elsewhere. If not, it could point to a solenoid issue.

This will help narrow things down so you can get closer to the root of the problem!

I am having trouble finding any of this stuff. This is a 2017 CC Precedent 48v (JE) and everything seems to be behind covers I can't figure out how to open. There is supposed to be a fuse in there and I have the motor access cover off but I am not sure how to get into that box. I assume the solenoid is in there too, The MCOR has a cover on it too and I am not sure how to get that off. This is pretty frustrating. Thanks for your help.

The main 15a fuse should be near the main harness near the controller or solenoid, some precedents you need to access it from under the cart. There is also one attached to the run/tow switch. Here are a few diagrams with the fuses circled along with the MCOR access panel breakdown.

Thanks again. I found all 3 fuses except the round one is nowhere near the tow switch. It is in the bottom of that compartment. They all check OK with a meter and the blade fuses you can see through are not blown, bummer. I was hoping it would be easy. In my looking I found a metal hook hanging down and it turned out to be a battery hold down that rusted through so I spent some time there. (pulled a battery to see). Then I had to go help a neighbor fix his truck It was getting late so I am going into the MCOR tomorrow. Since that is likely the thing that went under water, I suspect that is my problem. I will know more tomorrow. These things are strange to work on. I don't think they built any 2 alike. Something is different than the picture, no matter what I look at

[gfretwell]

I found a 2016 maintenance manual on the web and that seems to match what I have fairly well. After about 4 hours of checking different things I figured out what I was trying to avoid. Bad controller. No ground out of the controller for the solenoid. If I pull the Bl/W and ground that terminal it picks but the cart still won't run. I have the 48v in on pin 9 (gray). On the MCOR I am missing the 5v from the controller. I even tried hooking up an external 5v thinking I may have just blown the PS in the controller but no joy. The only thing I didn't try was to ground the solenoid and put 5v on the MCOR at the same time but I doubt that would work either. I am just getting a controller.
Thanks again for your help.

Thanks for the update. The controller requires all inputs to be functional before it activates the solenoid. Out of curiosity, what was your result checking voltage with black probe on pack negative, and red probe on controller pin 6 green wire, (with plug still attached to controller), with the cart in RUN, key ON and accelerator pedal depressed?

I was getting 48 out of the switch. I used the chart and checked all inputs listed on the 16 pin connector. They were all good.
I have been in the fix'n biz for over 50 years, 30 with IBM. At the end of that I was more into why things fail than what's bad.
From what I found out today about this cart. I ran off in the water, shorted out the 5v, which is also the VCC for the processor in the controller and may have blown a land pattern but it also killed the power supply. When I hooked up the 5v, my guess is it never got back to the processor.
Have you ever taken one of these controllers apart? I see them being repaired but I assumed they were potted. I bet this is a garden variety DC/DC converter chip.
I do have one coming tho

Thanks again Greg

[golfcartg]

Well done! There is a guy repairing a Curtis 1515 on youtube recently, I will try to post the link here

[golfcartg]

[gfretwell]

That was pretty cool. Since I don't have a core charge on this I will crack into and see what I see. I wonder where he got the schematics. That one picture just looks like an H bridge, maybe a high level representation of the motor drive.
I wonder if they are really getting 300a out of a few TO-220s or whether there are some big drivers we didn't see.
I am thinking about redrawing that diagram in the manual to make it easier to read, maybe something more conceptional.

[gfretwell]

How much do I have to worry about programming. Is the default setup up good enough for the casual user? Can a dealer program it on the bench? I am not going to try to buy a hand held.

[golfcartg]

If you do dig into the controller it would be fantastic if you could grab a camera and create a thread with pictures in your spare time. There isn't much documentation out there on this topic and sharing your findings would be great! By the way, if you haven’t already looked into it I wanted to mention that the dealership can install speed code 4 for a nice bump in speed to about 19.5 mph at $100-$150 or less. The controller programming software is floating around here and you might be able to handle it yourself about half the time and half the time it will not work, need to fabricate your own cable for connection.

[gfretwell]

I will look around for the software. I do have a neighbor who is a dealer. I may just pay him to set it up the way I want it. If I do get in that controller I will post what I find.

I was looking for info on the controller and I found a test we didn't do. Hook up the charger to wake up the OBC
No joy but I let it charge a while. I had pack voltage on pin 5 when I unplugged the charger. That seems to be the charger interlock. I have it on the bench now but I got no insight into how to open it and I may be able to get $60 for it from a rebuilder if I don't screw it up. I am going to pursue making a programmer. The install manual is interesting. I have the PDF

Have you managed to get all of your controller inputs sorted out? I'm curious how things are coming along, did the replacement controller arrive yet and if so how’s it working out so far? There might still be a few more tests we can run if needed, but it sounds like you're making progress.

They are saying I won't get the new controller until next week but from all the testing I have done, I am sure it will fix it. I have quite a collection of information on ERIC Precedents. I will put it all up on my web page and link it here.
