How to Repair a Couple of Wiring Harness Problems

And I do not understand the big deal about bypassing the........ gauge....... really is like a big bypass anyway - internally there is a brass strip the connects the two terminals. ..................

Ok, because you don't understand, I will explain.

There IS NO brass strip connecting the two terminals. At least not guaranteed to be. THAT is the problem

I assume you have glanced at.........but not read.......this?

Does this look like a good connection between two terminals and a brass strip to you?

Didn't think so. As soon as I saw that photo a few years ago, I was instantly transported back in time........to the mid to late 70's.........when everybody "up here" was throwing heavier alternators on their pickups............and winches.........and electric / hydraulic snowplow hoists.......and pulling RVs.......with trailer / RV battery charging lines.

The fact is, there is NOTHING except luck connecting the two terminals and the brass strip which are three separate pieces. they are not crimped, soldered, brazed, or even, really, bolted together. The bolts (depending on the year) are sandwiched between a layer of the THERMOPLASTIC that forms the cluster housing. In the photo above, I can tell you exactly what happened............the terminals got a little loose in the plastic, then got warm.......and then.........

I'm not even a commercial mechanic, but years ago, I "got" a reputation and found myself tearing clusters out of local pickup trucks
