Alternator wiring

dartsixty7 said

Yes, the voltage regulator I have installed is an electronic voltage regulator that looks like the old style ones. I thought I had to run a wire from the second field post on the alternator to the ignition post on the voltage regulator? I thought you only grounded the second field post if you were keeping the old regulator and didn't have electronic ignition. Could my problem with the amp gauge be because I didn't splice into the wire but instead used a splitter to attach the 2 wires to the ignition side of the voltage regulator?

Thanks for the replies

Here's how I did this conversion on my '66 Valiant with electronic ignition:

Electronic regulator that looks and wires like the old mechanical one... Check!
Newer square back alternator with 2 field terminals...Check!
Wire from one field terminal to ground. (Turned out to be about an inch long. It only has to go to the alternator case)...Check!
Connect old alternator wiring to the appropriate terminals on back of alternator...Check!

Yes, it really is that simple and has worked fine for 3 years now. Replace the wire you added with a wire running from the field terminal to the alternator case and you are ready to go.
