amp gauge

Personally, I have had my amp gauge converted to a volt gauge, added a 75 amp alt, 8 ga charging wire. My charging wire goes directly to the starter relay stud, so that is the main buss. Also the original blk/red wired that went into the bulkhead for the amp gauge, are now fusible links put together and go the starter relay stud for power. I have relays for the headlights, so ALL heavy loads are NOT inside the car.

Even if you get an upgraded amp gauge, its the bulkhead that still gives you an issue. It creates a "shunt" and can only truly handle 55 amps MAX. The more splices, the more resistance, soldered or not.
