PLEASE HELP: Converting from External to Internal Voltage Regulated Altenator

[grif]

VetteVet, you've been a great help. Using your pictures and diagrams, I believe the problem was that the previous owner had the F and R wires switched at the regulator. I was getting a little less than 13 volts on the battery with the truck running. After switching the F and R wires on the regulator, my new reading is up around 14 volts.

The white wire does appear to be the exciter wire; I have gauges (not idiot lights) and this wire has zero voltage on it with the key off and 12 volts with the key on. This wire is connected to terminal 3 and jumpered to terminal 4 on the regulator.

I do believe I would like to convert to an internally regulated alternator. Can a mod please move this thread in the electrical forum? Since my voltage regulator is unusually wired, I'll need a little help.

Thanks!
