Got ya man, same thing happened to me at the beer warehouse... They pressure washed the truck, ac type drive motor, blew a transistor pack behind the capacitor board in the drive controller compartment on the left hand side with all of the boxes inside, had to remove the whole controller panel, bus bars, everything. This little cutie cost a thousand dollars to replace, and there is 3 of them, it is called the tmd, transistor, motor drive, it was cooked!!! It takes alittle time, and alot of masking tape, but it can be removed, just waiting on the part now...
