2007 Yamaha Model YDRE 48 Volt

Golf Cart Won't Run In Forward or Reverse. I have replaced all the batteries, solenoid, stop switch, throttle sensor, controller. I hear what sounds to me like a little humming noise but get no movement in either direction. Cart started shuttering and then quit moving in either direction. No bad noises from the motor or rear transmission prior to that.

Is it possible that a faulty forward\reverse switch cause the golf cart to not move in either direction????

It sounds like you’ve replaced a lot of components already but it’s often more effective to use a digital voltmeter to test parts systematically rather than just swapping them out and hoping for the best. If you’re up for the challenge, you can locate the issue with some guidance and a bit of testing.

Start by checking if you hear a click from the solenoid when you cycle the run/tow switch. This click indicates that the solenoid is engaging via the controller. Next, put the cart in reverse to see if you get a buzzer sound. This will confirm that the forward/reverse feature is likely functioning correctly. If you don’t hear the buzzer, a different approach may be needed.

From there, you can follow this attached flow chart to narrow down the problem. Make sure to refer to the correct section based on your symptoms: “Solenoid Does Not Operate” if you don’t hear the click when you press the accelerator pedal, or “Solenoid Does Operate” if you do hear the click but still get no movement. If you need any guidance along the way or run into questions, feel free to ask!
