Re: Alternator & External Regulators
There are a couple of ways to do the new Alternator with or without a External Regulator.
- 1 Wire Alternator with an internal Regulator
- 3 Wire Alternator with an internal Regulator
- Stock Type Alternator with an External Regulator
If you convert from the external regulator alternator,
you no longer need the regulator that is mounted on the radiator support.
You also don't need some of the wiring that is present in the loom.
Replace original 10 gauge main wire from the alternator to the horn relay with a new 8 gauge wire.
Also, do the headlight relay conversion, this will make a big difference when powering halogen bulbs with full voltage.
I have a word document that provides more detail on the following;
