Thread: Wiring question voltage regs.

Tweet

i have a GM alt on my mustang .. i use the tie the two wires coming out of the pig together and use a diode to prevent back voltage then join the big red wire and head for the battery technique .. .. if you cant get anything else to work look up onewire alternators on the web and the system i use should pop up ... surely your stock wireing is`nt butchered up so as not to allow you to remain near stock though

OK I have decided to go to the internal reg. Alt. A GM 3 wire.

I would like to keep a working GEN Light if possible.

How should I go about doing this. What are the connections on the '73+ for?

Thanks

I have read the following site:

I am a visual learner and think that I have found the solution. What do you think

(this is a modified drawing that Denny provided. Do this look correct. it seams to easy )

Here is a close up if you can see it of the proposed changes I want to make.

If it is really this simple, everyone should do it. It would make sense why GM did it.

Thanks for all of the help. It will really clean up under the hood.

It was really quite easy. Thanks for all of the help. The wire that I thought was yellow was really white. Most of the wrapped wiring was still in the factory cover and the wires looked great.

Here is a pic. I have since rewired the blue wire into the boot of the red wire. I wanted so bad to test so I threw a piece of electrical tape over it and tested it.

P.S. I have a "tall" (original style) external regulator and the factory plug with about 12" lead if anyone would like it. ( you pay shipping )

Again, Thanks for all of the help.

If anyone needs I can do a step by step.
