92 G8 diagnosis needed.

[Simple cart]

Ok, if anyone remembers my previous post, i am starting a new thread. I have a 92 g8 cart (thanks guys (and gals if there are any) for help finding out what it is) it either has a short in the wiring, or the computing board is bad, or is it possible the cylinoids went bad just from sitting over a winter?
I bypassed the board, cyllinoids, and wiring, and it went backwards and forwards on its own power with 3 12-volt batteries in it. Admittedly, it went forward and back by touching the batteries straight to the f/r switch, but it worked XD now all i need to know is how to test to see what is bad. If this thread gets no response on how to do it, i will start by rewireing most of the cart. Anyone got any ideas?

Follow the wiring diagram. See where you have the issue before you start randomly replacing parts. If you jumped through the F/R switch to the motor and the motor ran you've confirmed those two parts function. Lots of other possibilities: Ignition key switch, pedal stop switch, limit switches, solenoids and every plug and stretch of wire on the cart.
