2009 Club Car Precedent 48 volt. It has a dead spot on acceleration. Goes along fine for fifty yards then loses power. Let up on accelerator and it goes again. Batteries test good on a load meter. I replaced the Mcor throttle potentiometer thinking that would solve the issue but it didn’t.

What else could be the issue? Thanks in advance!

Check all your wires and connections for corrosion. Electric gremlins on electric golf carts can be fun. I had my headlights not working. Replaced the switch and still had the problem. Ended up being a corroded (hidden) wire.
My EZ Go seems to eat wires. My parents Club Car not so much. Go figure.

This is a great forum for everything golf cart related, EZ Go, Club Car, I use it for issues with my Club Car DS.

Lots of good people with knowledge on just about every model out there..

I'd try hooking a volt meter to the input of the controller & see what the voltage is doing when it drops out. Something is causing the controller to fault out. You'll start out at ~50v or a little above, then it will drop when you push on the accel. It should level out & then climb as the load decreases. If the voltage drops quickly at the same time as the controller cuts out, you have at least 1 battery that's going bad. If it's steady/climbing slightly, the controller or downstream is the cause. Since it's resetting, I'd suspect a safety acting out. I think EZGO has a speed sensor that will cause similar issues. Never had to look too deeply on that side.

What's the load & voltage drop under load? Most battery testers are aimed at automotive starting, so ~100A for ~5s approximates that. Under acceleration, your cart could be pulling that for a lot longer, a weak battery could cause issues.

Uhm, sounds like the throttle potentiometer has a dead spot.

Are you near Brainard?

No help to the OP, but had to get a chuckle from my initial read of the title:

Trouble Shooting Electric Golf Cart

First thought: aim for center mass

Or try 10mm.

If it's just slowing down and not quitting then it is likely the speed sensor, if it stops then probably solenoid

For a minute there I thought you were having optics issues with your rifle.

Trouble Shooting > troubleshooting

Came to say the same.

It's always a painful time when the cart's time comes and you have to put it down, but it's for the best.

You thinking Paul Bunyan can fix it? Oh wait, that's Brainerd's neighbor to the north, Bemidji.
