Electrical Issues

[Nerfgit]

Hi, I'm looking for some advice after getting scammed by a shop. My 86 SVO has an upgraded alternator done by previous owner, however, the breaker keeps blowing, I poked around the engine bay and found the voltage regulator wasn't plugged in, but now my alternator light on the dash comes on and stays on, even if I take the keys out of the ignition.

What I want to know is how do I figure out why the breaker was blowing, if I I need the voltage regulator plugged in (I assume I do) and finding out why my alternator light is on and stays on, and is the solution a 1 wire alternator

Thanks for any advice, I really appreciate it

One of the first things you need to figure out is the alternator a 3G or a 6G style. They have a different wiring setup depending on which one you have.

The next thing is to determine if the previous owner replaced the factor wire that goes from the alternator output to the battery side of the solenoid. If it is original, it is to small a gauge and the connector is a known weak point. Mine caught fire with the original alternator before I did the upgrade.

I did the 6G alternator upgrade which required removing the regulator and making jumpers for the regulator connector to make it all work.

If it is a 3G install, check this thread out.
