Cat Lift Trucks (& Caterpillar) M50D SA:
ERROR CODE F-2

I have a M50D with the above code. I have disconnected all three of the IGBT'S with no affect. The minute you turn the key on you get the code. Drive motor was just rebuilt and a new battery installed. Is there away to check T1D and T2D ? All contacts are open and all diodes have been checked. Any suggestions ?

Thanks In Advance jjr
