No but I did reverse the leads. I actually found out today from a friend. This unit MUST be on the ground and have weight on the front wheel. It needs the resistance during startup test. As soon as i put the drive wheel on and put it on the ground all faults went away. This will never happen to me again. I wasted 2 days trying to figure what was going on and to find out it was becasue of something so simple. But thanks for the reply. Bunky
