Thanks Ray,
If your referring to that 1 of 2 square componets on the back of the control panel below the 2, 220v twist locks, I've already replaced it and still no luck. The thing is is that I can't even read voltage out of the head leads on the power side or the welding side, no dcv either. The 3, I guess commutators on the armature are worn a little, but not bad enough in my opinion (whatever thats worth) to affect it that badly. Brushes are seating well too. Any other ideas? I've heard some talk about motoring the unit. Is this a possibility?
Thanks You,
