How to Repair a Couple of Wiring Harness Problems

I usually pull the harness and remove each female connector, wire brush eacg with a small dremel wire wheel , bend the catch tang back up, grease it and slide it back into place til I hear it snap into place. Good to go for many more miles. The heavy black from the alternator and heavy red from the battery usually have that melted hole issue. You can bypass them both like the factory did. And I do not understand the big deal about bypassing the alternator. The gauge really is like a big bypass anyway - internally there is a brass strip the connects the two terminals. The amp gauge needle isn't connected to anything - it moves due to the flow of current through the wire like one of those current testers you just hold over a wire to look for a short.
