Club car surges

Ever turn a radio knob and hear static? Sometimes when your turn that knob back and forth several times the static will go away. By doing what you did it was cleaning the contacts inside your MCOR/Pot. It might last a long time or begin to repeat your issue, only time will tell.

It's not permanent. It's a pay me now or pay me later fix.

What is not permanent, did I fix the mcor or the speed sensor?

Mine was doing the same and that trick so far has worked well been about 3 months.

Neither...

You just helped to clean the contact surfaces as shown in the pictures attached.

Your MCOR is a sealed unit and they do go bad, mostly with the Micro switch inside.

Neither has anything to do with your speed sensor.

I just read another post from a guy that said he left the key in the off position and he hit the go pedal 20 times and it worked for him to get rid of the surge. I was told to do it with the key in the ON position and in neutral and it seem to work for me so will it really work with the key in the off position also?

The key has nothing to do with cleaning the film off the wiper. It would work on or off f n r just would move the cart some if in f or r and the key was on. Like stated above you are just doing the same thing as turning a radio knob back and forward to help with static.

FWIW, I just tried it on my HuntVe and it worked. Key on, put in Neutral, and pump the throttle. It's now smooth again. I guess I could have just worked the gunk off the contacts but sure seemed to get all the gunk off the entire sweep of the throttle. Anyhow, thanks!

I was just reading ken baur's post about calibrating the mcor to the motor and I must say it worked like a charm . this site is awesome ,excellent advice ken saved a bunch of time with a troubleshooting headache
