Default Club car surging issues.

SN-A0101-977894
Resting
PV- 51.3V
Individual batteries all 6- 8.4~

Under-load driving FULL THROTTLE
Pv 49.7
Individual all 6- 8.3~

The issue comes with driving, doesn’t matter the terrain(mostly flat) the speed is slower than others, while going Full throttle it will surge intermittently for approximately 3-10 seconds to the usual golf cart speed of 11-13mph. The surging is not consistent enough for me to get a good grasp on the problem. I’m at a standstill on the issue. I have jacked it up and had probes on main neg and b+ and get full PV at resting and gradual decreasing V as I depress the pedal. Which to my understanding is what it’s supposed to do. Any ideas from the techs? I’m open to trying it all.

Try putting it in neutral and pumping the accelerator pedal 20 or 30 times. That often helps surging on a cart with an MCOR. I'm not sure if it will help with yours but it certainly won't hurt. It helps clean the potentiometer coils (in the accelerator).

That's an '01 Bruce, it ~should have a variable speed potentiometer (V-Glide) on it...

But to your point, it could have a burnt contact on the pad, too.....

No it doesn’t have an MCOR, it does have the pot’ pads have been cleaned, I was afraid of it being the brushes just didn’t want to admit it to myself, Well to the golf course anyways. How bad is that job? I mean opening it up, replacing, cleaning and reinstall

It is not too bad, but be ever so careful removing the cables so you do not bust the lugs/posts. Double wrench everything.....

Any small motor shop or starter/alternator shop will do it for you....

So I was doing a motor swap with another cart they have laid up and and just to add headache to the hole process a motor stud broke attempting to remove nut. Didn’t break inside just snap the actual stud

I did double wrench everything but that’s life working on these ride hard put up wet carts
