How to Repair a Couple of Wiring Harness Problems

Silicone di-electric grease at any auto parts and maybe Ace Hardware. I use a small flat file (Harbor Freight kit) w/ sandpaper wrapped around it to clean the female terminals. The males can be removed (squeeze at base longitudinally) for easier cleaning.

Melted ALT and BAT terminals are common in all cars except 63 & 65 (why?) and those w/ "fleet bypass" (taxis, police). Bypass the ammeter or use my diode shunt method to keep it active at lower currents.
