So next on the list is to ditch my generator for an alternator. I'm going to keep my Ford a Ford. The problem is I've always used a Delco three wire.



I know what "BAT" is. I know that one goes to the + on the starter solenoid.



Next is a post (marked STA) with a white wire.



A post (marked AA) with a green wire.



Then a pigtail with a red wire (marked CC)



Finally a stud (marked BB) with a black wire. I assume this is a ground.



So thats the alternator back. I was told to take the wire from the AMP tab on the voltage regulator and combine it with the wire on the BAT tab. Then connect the larger gauge wire from the generator back (BAT) to the BAT post on the new alternator. I don't have an idiot light in my dash for the generator but I want one. Can anyone tell me how to wire all this up correctly?



Made all my brackets tonight just need to get it wired. I hate electrical. Thanks.

Steve, that was a good write up but I've still done something wrong.



I removed the old generator. I hooked the 8ga wire that was on the generator to the BAT post on the new alternator. That wire runs to the BAT post on the old voltage regulator. I also moved the the 8ga wire that was on the ARM tab to the BAT tab on the voltage regulator. So I have two 8ga wires on the voltage regulators BAT post.



Then I connect the old white wire from the generator FLD to the red pigtail on the alternator. That wire runs over and is connected to the wire leading to the GEN dash light. If I turn the key with this setup I do not get a dash light.



If I take the wire leading from the pigtail (old white wire) and the wire leading from the GEN dash light and connect them both on the FLD post of the voltage regulator I get a GEN dash light when I turn the key. But the light stays on when running.



In both cases the engine will die if you remove the POS battery cable. So its obviously not making current. I was told to wire it this way if I wanted to keep the voltage regulator for appearance. I'm stumped, I followed the directions I was given and its real similar to a Chevy setup.

Theres a wiring diagram on a previous post.Basically it should be wired this way. Alt "F" to "F" on regulator.Alt "S" to "S" on regulator.Alt "B" has heavy wire to battery side of solenoid.Second wire from "B" terminal on alt to "A" on regulator.This needs to be 2 completely separate wires.Dont splice 2 wires together.  Ground on alt to good ground."G" on regulator to ground. "I" terminal on reg. is the wire to dash light.If you check this info against what you have done you should find the problem.
