It would help to know the year of the vehicle.Hi I'm searching for a part number for the complete alternator wire harness from the main 12volt pig tail to the relay box
The main output of the alternator runs directly to FL MAIN and to the battery.On a 95+ the charge wire is split in two branches. One branch goes to the AM1 block, through a fusible link and lugs down to the battery post.
The other branch goes to the fuse block next to the DS fender behind the charcoal canister.
This branch is often referred to as the alternator good signal. It’s the power line I’ll be using to ensure the pump for my intercooler will only run if the engine is running and the alternator is working. I’m sure there are other uses but that’s my use for it.
sorry 1997 fjz80It would help to know the year of the vehicle.
Also, the high current output of the alternator runs directly to the fusible link off the battery, not the relay box. The logic side of the alternator is part of the main engine harness.
so I went out to a truck I have and took a couple of pics of how the wiring is ran from the alternator.The main output of the alternator runs directly to FL MAIN and to the battery.
The sense wire off the regulator runs to FL AM1.
The branch you refer to as running to the relay box is for the charge warning lamp. From the regulator, pin 1 will go low to illuminate the charge warning lamp as it's getting +12 from the IGN fuse.
