Where can i find the wiring diagram for 2001 pathfinder Alternator. I started up my car this morning and my voltage is around 12.4. I check and the vehicle is running off only the battery. I just want to check if any fuse blow before i remove the alternator.

the alternator is self-contained. replace your alternator. you can get them on eBay for pretty cheap.

Do you have battery voltage at the S terminal on the altnernator? That's fed through fuse #65. If you do have battery voltage there, replace the alternator. They run about $99 at the auto parts store.

There's a fine wiring diagram in the FSM.

I did check the battery voltage before replace the alternator and it was around 12.4 volts. I replace the regulator on the alternator. That resolve the problem. Now the vehicle idle at 14.4 volts.

thanks everyone for there help.
