02 Club Car : Stalls Frequently

[russhull]

Hello All,
I have been searching the forum for people with similar issues and have not found anyone that comes back to say this is the solution.

This is gonna be a little long so please bear with me and I hope someone can help. While driving our golf cart it intermittently stalls and the coast beeper comes on and we coast to a stop. We take our foot off the accelerator and push it again and it runs just fine for a short period of time and it does it again. Sometimes it happens 10 times in a mile, other times just twice.

Based on other issues, I figured it was the MCOR which I replaced over the weekend (Version 1). I found a V1 on Amazon so I did not have to do a conversion and my cart is old enough that all work has to be done from below.

When driving I hear a "click" when it starts slowing which if I were to guess it was like someone was pressing a button and their figure slipped.

The early IQ models had an error condition called "main drop-out" that was triggered by the controller activating regen brake to limit the speed.

Club car no longer sells the "main drop-out harness" that plugs to the Tow/Run switch to fix the issue, but since it is just a diode, you can just solder one on the wiring to correct the issue.


Get a 10 amp diode like this:

Cut the gray wire a few inches away from pin #9 at the Controller 16-pin connector.

Solder the diode inline with that wire, the diode stripe side goes toward the Controller 16-pin connector.

Thank you Sergio,
I am ordering the diode now and will work on this over the weekend.
Thank you and wish me luck!

FYI....
It looks like this worked. After doing exactly what you said, I drove it for 10 minutes with no stalls whatsoever.

Do you have a donation page?
thanks again for the outstanding response

Thanks for the update. Solenoid dropout is fairly common with these first year (2002) IQs.
