Re: Spikes

A couple of years ago, we had a system where we kept blowing up Victors. One would blow, and we would replace it. That one would blow, and we would replace it again.

After doing this costly replacement routine a few times, we found that one of the wires between the motor and the Victor was contacting the robot frame, providing a nasty short. It took us a while to find it, as it was intermittent. After a few continuity checks, we found the culprit, islotated the short, and fixed the problem. No more Victors were fried.

Denman... maybe you have an intermittent short to the frame, or a unseen short to some other grounding device. Trace those wires, make sure they are all insulated and isolated.

Good luck,
Andy B.
