Solid state conversion problem

[Dieselnut]

Im finally done with my solid state conversion on my Royal Ride ('88 club car chassis), but Im confused as to the correct wiring for the high current connections. The dealer who sold me the Curtis 1205-5603 controller gave me a diagram to follow(attached), but something isn't right.

The car will run briefly, but then the controller seems to go into a protect mode of some sort and I have to cycle the key off for a minute before it will go again. I tested everything from each contactor to the potbox and all checks out. The only issue I see is when testing voltage across B+ and M- I get nothing when the pedal is depressed.

Th D&D motor says:

Connect S2 and A1 together
Connect S1 to battery terminal
Conmect A2 to other battery terminal

Anyone know which is the correct wiring? I'm new to EV wiring, not sure where to go on this one. Any help is much appreciated!

Both the main and the f/r contactor click, but motor won't turn when the problem happens. If I wait 2 minutes, even without cycling the key, it will work again.

Frustrated to say the least....anything I can test for? Problem is that I only have less than 2 minutes to use my meter and test before it starts working again.

Hooked up status LED. It will run 4-5 drive cycles then will stop and flash code 2,3 twice (which is for HPD lockout) then goes to code 1,4(which is a generic wiring problem.

I thought maybe the keyswitch was bad so I bypassed it, same problem. Could it be a bad potbox or microswitch? Just not sure how to test, as the problem is somewhat intermittent.

Anyone have any ideas of where to go from here?

You said you connect S2 and A1 together? I don't see that on your diagram, and also i don't believe i've seen that before?
