Intermittent quits and won’t restart

Papas 73Dart · 05-30-2020, 01:37 AM

I have a 2001 DS that runs great most of the time however occasionally when slowing down a bit and then depressing the throttle pedal fully the cart won’t re-engage the motor . Then I have to completely lift my foot and depress the pedal you hear the solenoid and it goes just fine . Today same thing only there was no re-engagement of the solenoid and no motor function! Had to push it home after multiple attempts to start.
All cables clean and tight batteries fullY charged but nothing!
Let cart sit an hour and tried again solenoid clicks and motor runs .
One question : is there a test plug outlet on the controller to plug in a Curtiss scan tool?
Should i test the old mcor, if so whet are the voltage values at each wire?
I don’t have access to a service manual so just help me decide where to start looking

What is the serial number...

Papas 73Dart · 05-30-2020, 08:34 AM

Serial #AC0118-014483

When it runs the pack voltage goes from 50.2 v down to 47.5v on the flats i.
It quits when you take your foot off the throttle at a stop then step on it again .
Sometime you hear the solenoid click and disengage immediately ather times you hear nothing then the next time it clicks and runs just fine.

Not sure, but is there a test port just below the FNR switch?

Papas 73Dart · 05-30-2020, 05:24 PM

there was no test port it has a GE controller

fortunately I parted out another 01 DS two years ago and saved the electronics the motor had burned up and some of the body was wreaked
I tried the MCOR and it seems to have solved the problem .
Just to make sue I drove it around for half an hour and did hundreds of stop starts without missing a beat.
thanks for the reply

99% of the time it's the MCOR when it comes to CC throttle issues.

Glad you got it figured out

Hope your problem is solved. I had one doing the exact same thing. Drove me crazy trying to figure it out.

Wound up being the key switch acting up.
