Alternator and Voltage Regulator Questions

I often refer to "functional path" but bear in mind current actually goes from neg to pos.

But the "functional path" originally was centered at the welded splice

If the engine was stopped, the functional path was from battery....fuse link....through the bulkhead connector........through the ammeter.......to the welded splice.........and branch off to ignition switch/ accessory hot buss, / headlights etc

If the engine was running and charging, the path was from alternator.......through the bulkhead...........to the welded splice........and off to the loads as above........through the ammeter........through the bulkhead connector.........and to the battery (if / when charging)

EVERY SINGLE POINT mentioned above is a potential for voltage drop if they are diminished, including the welded splice which is rare BUT they HAVE failed!!!
