I have a question can I change the alternator out for a alternator without a external charge regulator but with a internal regulator that way I can do away with a lot of wiring

Try running it w/o the regulator-Is it still overcharging if so you still have a wiring problem between the regulator and alternator

What's your problem -there's no ground circuit to charge indicator it comes from the ignition switch thru the indicator and back to the alternator for field excitation. Right now you're lost in the woods and you need my help that's why I responded not trying to be a ( bad word )

You got 4 wires going to the voltage regulator IASF there's no ground there the alternator housing provides the ground
