power wire (the one that gets power when key is turned on) - is the one you'll have to connect the regulator to. I don't know enough of words in English to explain how exactly it works but i'll try anyway lol. Alternator must get some initial power to that terminal to start working (+12V), and after engine start voltage on that terminal is to be regulated for constant alternator output voltage.

 

OK.. So i bought the regulator today.. I have it right here in front of me.. Ive found a picture of it and marked what each post is marked on the actual regulator.. so it looks like this



Theres a I post A post S post and F post..

I found this diagram online


Which explains how to wire it pretty good.. the only problem is this shows the alternator with a "feild" and "stator" wire going in.. but mine only has 1 power wire.. I made a diagram of what the back of my alternator looks like



Any ideas of how to wire this thing up?

 

Ok, I have absolutely no idea why did they call that thing "field". I can only imagine should be going on inside of an alternator according to the fact it has a field (and probably a farm?) lol. Ok, now seriously. I think that "A" post on the regulator should be connected to the wire from ignition switch, and "F" post (i like to connect fields, i really do) should be connected to the alternator "power when ignition on". Why this way - usually alternator output is adjusted by changing a voltage on brushes, and brushes conduct electricity to rotor, not stator. Do you have any idea why on wiring diagram there's no ignition switch? It really confuses me... According to logic - it should be in the middle of Y/W wire...

P.S. Sorry for my poor English...

Update - "S" post of regulator is used for instrument cluster lamp operation is some alternators. It is really to be connected to the "middle of the star" of stator. In your case i think it should be left unconnected.

 

I got it wired up.. it works great now..

I took the alternator off and discovered the extra stator post so I made a whole new wire harness out of 12 gauge wire, I ran the F post of the regulator to the Field post on alternator, the S post of regulator to the Stator post on alternator, the A post ran to the battery out put then a wire from battery output to the positive battery terminal.. I ran the I post to the 12v ignition wire in my radio harness, and I ran a new ground from the frame to both the regulator caseing and the alternator

Its seems to be working great now.. no more overcharging

 

Good to hear you have it fixed

 

Any voltage over 15.7 can fry wires

 

well i got it all sorted out now.. it works perfect
