I managed to cut the lead cord to my 12v air compressor without marking the +/- sides. If I crosswire it, will I damage the compressor? Make it run backward? Suggestions? Thanks.
Examine the wires carefully. There may be a mark of some sort one of them. Look for ridges or such on one wire that isn't on the other one. If you wire it backwards you will probably blow a fuse, I think that's the worst that would happen. Good luck
