It runs but the stock alternator was failing. I have an N350 alternator from a S5 N/A RX-7, I have everything installed but the wiring harness. The factory harness has 3 wires going to the back of the alternator, the N350 only has input for 2 wires.

Few questions:
Which wires do I need to connect to the back of the alternator? And where should the 3rd wire go? Do I have to jumper the regulator connections or simply disconnect it?



Thanks guys.

 

congrats we need pictures for proof

 

In for pics

 

Anyone with answers to my wiring headache? I know there's a wrong way to wire it and I definitely don't want to be replacing wiring harnesses this early in the game.

Here are pics of the REPU:

 

I believe what I did with my REPU was use a keyed hot wire to excite the field and the other to go to the factory ammeter. It's been a long time though. Here's some links that may help you out.

I think that first link is going to help a lot, thanks!

 

this is what i did

 

quick fix on the alternator is to run a wire from one of the igniter (12V) and connect it in back of the alternator (upper pigtail). this will trigger the altenator's F terminal to start charging.

My desktop crashed and Im unable to recover my old stuff (pix and notes). Either search under my SN or PM Jeff20B. You have to disconnect the voltage regulator and then run 2 jumper wires but I cant remember which wires.

 

 

Great, I can't wait to finish this tomorrow and go drive it again.

 

you get this from guy in kansas?

 

Yeah.

 

Sweet, everything is working besides the G light. But I'm not really concerned about that quite yet. Thanks again guys.
