I have a LS1 swapped RX7, and I have obvisouly misssed something......

It is a 2000 LS1, with stock computer, and 1 wire alternator. But the alternator is not charging, so obvisouly the excitor wire isn't doing its thing.

The car is a pourpose build race car. So I am looking for a simple answer.

The question is instead of tracking down my issue is there a Self Regulated Alternator out there that fits the LS1, or are there any "Tricks" to bypass. I figured anyone that is running a carb since there is no PCM would probably know exactly what I was talking about.

Thanks for your help.

i have took and run from a 12 volt power supply when the ignition is on and run it through a type 194 bulb then to the alternator. when you turn the key on the light should turn on and when you start the car and the alternator starts charging the light will go off also serves as a warning light hope this helps

You can also run 12 volt switched power through a 470 ohm resistor to pin b and it should charge. If it doesnt then the alternator is probably bad.

You don't need a computer to run an LS alternator. If it is not charging then something in the hook up or the alternator itself.

Take it to autozone and get a free check to eliminate the alternator.

If it is a true one wire alternator, you only need to hook the battery up to it, since the regulator is self exciting. If you have the battery hooked up to it and it doesn't charge when running, there is something wrong with it.
