This, kiddos, is why your liberal arts teacher told you not to fool around with electricity or mechanical objects. Don’t cross the poles as the Ghostbusters once told you, it is good advice. The voltmeter still works but since i can’t tighten the now fused nut on the red wire I will replace it shortly with a new one, and be more careful when installing. Would be a good idea to have some type of cover once the first is installed – like a simple electrical tape wrapping.
