FSIP.biz sells rebuilt cards to fix this problem
(they also have the tech manual for it as a FREE down load).

To the OP. I've found FSIP to be a great resource. They have a forum there as well so you might want to post your questions there also and see what they say, but the suggestions made already are good ones. As for this old tech vs new controllers, these old controllers may be crude and bulky, but they have stood the test of time and many are still working fine. Parts and tech support are easily available as well. That can't be said for most of the new high tech EV controllers most guys on here are using.

I am intimidated by the difficulty of all this.

Called FSIP tech support who said they do not sell parts for this controller, only offer a re-manufacturing option. They declined to give me a cost and lead time estimate even though I read him specific information from the original invoice and spec sheet, saying he needed actual part numbers from the actual unit.

I will want to know if I find defective components, where can I find replacements since FSIP said they do not sell them? Are there any other options for repair other than shipping the entire unit back to FSIP?

Sorry to hear they weren't more help. It may be because the controller was a version built for EV use and not a forklift application. What is the voltage of the car? At least you still have a last resort option of sending it to them.

I don't know your space constraints, but looks like you could rotate the control so the lever moves vertically and attach a link from the lever to the front of the pedal.

I finally just looked at the pictures of his car. I didn't realize it was a Trimagnum build. Very cool! I've wished I could do one of those for decades.
