I think I fixed my problem. After checking all the switches and jacking drive and steer wheels off the floor I found out that only one drive wheel was driving and when I turned the good wheel would cut out. I took the main drive contactor out and cleaned it up (it had a bit of pitting and carbon build up on the contacts) put it back in and everything seems to work. I be taking out the other contactor next and doing the same. Happy forking!
