Electric EzGo going issues

[yellowroses2003]

If we push the accelerator more than 1/4 of the way down it will run for about 15-20 ft, sometimes more sometimes less, & it will stop moving. But if you only push down about 1/4 of the way or less there’s no issues. Any clue why this is happening?

When you push the accelerator more than 1/4 of the way down and the cart only moves a short distance before stopping, it suggests that there might be a problem with the throttle sensor, which is responsible for translating pedal movement into signals for the motor control system. This could be due to a malfunctioning throttle sensor unit, disrupting the signals sent and leading to premature power cutoff to the motor. However, without additional context such as the specific model type of the cart and any relevant backstory on recent maintenance or modifications, it's challenging to pinpoint the exact cause. If you have more details feel free to reach out! Understanding more about the cart's history and configuration could provide precise insights into resolving this issue effectively.

It’s a 92 electric ezgo, think it’s a marathon. We just got it a few weeks ago so don’t know any maintenance background unfortunately. Believe the model is 26281-G01.

We'll need to start with some data gathering. First things first, make sure your cart is fully charged up. Charging it to its maximum capacity confirms that we're starting with a consistent baseline. Once it's fully charged let it rest for about an hour. This resting period helps stabilize the batteries and gives us a more accurate reading of their condition.

Now, we need to take a close look at the large connections in your cart's electrical system. These connections deliver power from the batteries to the motor and other components. Grab your camera or smartphone and snap a photo of all the connections you can find. We're talking about everything from the battery terminals to the motor connections. To make things easier for both of us, be sure to label each connection. This labeling will help you reinstall the connections later.

With the data and photo of your connections at hand, let's move on to the next step: performing a load test on your batteries. A load test is like a health check for your batteries, helping us understand their current state of health and capacity. To do this, you'll need a load tester. You can find one at Harbor Freight, and I'm attach an image for reference. Once you have the load tester, it's time to disconnect your batteries and get testing. Perform an individual load test on each disconnected battery in your cart. This involves applying a load for around 15 seconds to each battery and measuring its voltage under load. By doing this for each battery, we can assess their condition and identify any weak or faulty ones.

Here's why this information is important, it helps us understand what's going on under the inner workings of your cart. The results of the load tests and the photo of your engine compartment will give us valuable insights into the health of your batteries and electrical system. Based on this information, we can determine the best course of action to get your cart up and running smoothly.

Once you've completed the load tests and taken the photo of your engine compartment send me the picture and results. We'll review them together to assess the condition of your batteries and electrical system. Depending on what we find, we'll discuss the next steps to address any issues and get your cart performing at its best.
