That was great info ifmike, I have this code and found terminal 2 to only have around 5ish volts but I already changed the transistor and driver board prior because truck appeared to have a dead short, now that is not an issue and now I have this code. You mentioned not to use an after market driver board, I did and than when it didn't completely fix I did search and found your post, have you had a lot of bad luck with them, I'm a little nervous I can't eliminate it as the problem. Lucky me this was a non runner from an auction! Any help is appreciated, I don't have any manuals
