I have to admit I don't have enough electrical knowledge to follow this. I hope I can print this out and bring it to an auto electric shop and have them help me, at a cost of course. Or, just do what T2R9 did with the Sunpro gauge. I don't want to be a hack with the truck either. But his solution seems good.

Diagram "B" is the Mad Electric Ammeter by-pass.....
The lower schematic is the parallel circuit method that retains the OEM Ammeter. This was something that has been recommended over the Diagram "B" by-pass by member "Nacho" on another site.

So as I continue to educate myself on the trucks, I find that 72 thru early 75 trucks had a metal gauge pod frame, so no melting could occur. Maybe that's a good solution for inside the truck anyway. I see some on ebay. Pricey, but I plan on keeping this truck forever.

Diagram B is exactly what I did on my truck. The volt gauge is just using 12v from the fuse box and a chassis ground.
The Red/Black splice near the ammeter is just the two ammeter wires disconnected and tied to together. Where they come through the bulkhead connector is just removing the connector and using a continuous wire through it. The bypass is just a wire run from the Alt + terminal to the starter relay + terminal.
The mad link above is pretty easy to follow. The key is making good connections. If the wire looks questionable replace it.
B looks simple enough for even ME to follow. I like the Sunpro you used too. I read that even the temp controls can melt the plastic pod too. I just bought a metal framed gauge pod on feebay. Ouch, pricey, but this truck is staying with me forever and I love it. Still going to do diagram B like you did. Thanks man.

- EM Yes. Exactly. NachoRT is on moparts too, just doesn't check the Jeep/Truck forum often. The Parallel Circuit is simply a second wire from the battery, and a second wire from the alternator run in parallel with the original wires. If you find that illustration confusing, start here - http://www.heritech.org/cuda/Charge.htmlThen you can decide what you want to do.

Apparently the lower diagram method is exactly what Mopar did to get around the connector / ammeter melting problem once it was discovered. In other words, this is the factory work around and allows you to retain the stock ammeter and run a volt meter if you want.
- EM Actually, the metal base ones were on the pre late '75 model year trucks. Sometime early '75, in an effort to lighten things more they went to the plastic ones. You have to search for the older trucks to find one of the metal ones to buy.

Mattax; If I had read with a little more care, I would have seen he wrote diagram  . My fault. Thank you.
