Re: Car lost power when lights were turned on
If the engine was running during the wiggle test, it may be that the alternator is on the right side of the bad connection. Try the wiggle test with the engine off, key on. Perhaps it will reveal itself then. It certainly does act like a bad connection. Bad connections will get warm when you pull current through them. You might *carefully* feel a few connections after you've managed to load the circuit for a bit. They can get quite hot. An infrared temperature probe is a handy tool for finding hot connections if you happen to have one of those. Also look for signs of heat stress on connectors and wire insuallation.
