Ammeter heat question

The heat is directly proportional to the load.

At the ammeter wires if the battery is low of on its way out the wires will get warm, if the headlights are on they can get warm.
If you have extra non stock loads, fuel pump, electric fans, sound system, higher wattage than stock headlights, etc then you are pulling more wattage through the wire, than stock and it will warm up even more.

The simplest way to bypass the ammeter is to rout a heavy wire with a fusible link in it from alternator to starter relay post (assuming it is that way on your no a body car)

Leaving the rest of the stock wiring alone. That way you have two bulkhead connectors to Cary the load from battery or alternator into the car.


I would clean up the connectors at the bulkhead regardless, tighten up the terminals and check again.


Did you use any type of grease at the 2 terminals you tied together? You might have introduced a resistive connection there by using the wrong type of grease.
