Does anyone have any ideas? I've literally been through almost everything on this machine. I've tried different 1, 2, and 5 rec, capacitor, reactor/choke, took apart EV100 area cleaned everything checked all wiring to verify it is correct. Also tried different 4REC B, 1A contactor, and S contactor. Removed all cables that run from contactor panel to motors, pulled through the bulkhead cleaned inspected, reinstalled. I've tried a different steer motor. all the safety switches are bypassed underneath the pedals, steer switch, brake switch, entry switch. steer limit switches are working as they should, I can completely disconnect them and get the same results. height switch is working as it should , i can disconnect it also and get same results. forward and reverse switches have good voltage drops. All of my inputs to to the circuit board are correct. I tried a different circuit board, and the machine loses power it doesn't have the **** to do anything. It has a new: battery, circuit board, both drive motors, potentiometer, and both drive contactors.

The only thing I'm noticing that is when I'm checking for voltages, if I ground out to the frame of the machine, anywhere, I have strange voltage. Either ,-7, -10, or +25v.
battery voltage is good (36.84 @ connector).....
but (25v with pos lead on battery connector and negative on frame)

Does anyone have any idea or suggestions things to try, etc. because at this point I'm at a loss.
