Fusible link guage?

I'm 61, Mopars my whole life, since before I had a license. The terminals heat and cool , a lot, they loosen. Then anything can happen. No charge, no start, lights weird. Loose starts calling for more alt voltage, wires and connections get hot, etc.

Several times, traced down to loose amm wires. My 70 is bypassed, and who ever gets it, won't have to track down this old fix. Voltmeter!
