Re: Alternator fuse#4 keeps popping

Disconnect plug from alternator. Run engine. Does fuse still blow?

If you have a wiring diagram you would see the ALT fuse #4 covers far more than just the alternator:

AF heater relay
O2 heater
ELD
Cruise switch, actuator, and control unit
VSS
EVAP PURGE, CVS, and BP solenoids


*This is not a shopping list of parts to replace.
This is a list of things to inspect and test.
Don't ignore the wiring.

Check the wires to the O2 sensor. I had a heat shield come loose and wear thru the wires to the O2 sensor causing that fuse to blow.

This. My o2 sensor wires shorted out and kept blowing the alternator fuse too.
