So the deans plug shorted across the battery? Am I understanding that right?

I had an old BK system that had something wrong with it, It cogged so bad it literally ripped a round chunk out of the plastic spur gear. so it can happen.

I cant ever remember getting cogging from my R1s except for the time I had a capacitor wire break. If you are getting any cogging then there is something not right. Make sure the capacitor didn't get damaged in the short. Double check that all of your connections are still good. Not sure exactly how it shorted but if enough juice went through it to fuse the deans plug together you certainly could have melted a marginal solder joint somewhere.

I doubt that low radio batteries would cause cogging, but a main battery pack that isn't putting out enough current certainly would cause it. How long was the pack shorted? Completely fusing the deans together seems pretty extreme. Are you sure the battery is OK?
