Cat Lift Trucks (& Caterpillar) M40D:
Fault Code F 2

The forklift works for a couple hours then it randomly displays a F 2 Error code, thus locking down the machine not allowing any use. Only temp fixes are turning on and off (sometimes doesnt work) and some times having to actually un plug cord and plug it back in. This fixes the problem for a short amount of time and the problem occurs again. What causes this?

Any ideas on how this could be fixed? Me my self im not trying to fix it. The mechanic at work is. So if you know how and could just sorta tell me where to start i could let him know even maybe tellin him what you had said allready might clue him in as to what is wrong!

F2 could be By-Pass contactor tips welding/sticking (most common) since it is intermittent.
Drive transistors, Driver Board, Wiring problems.
