CONTINOUS BLOWN FUSES

2000 Ford Ranger • 6 cylinder 2WD Manual • 150,000 miles

Ok so I have a 2000 Ford Ranger manual v6 3.0L. A week ago the alternator volt regulator fuse blew. I replaced it along with the battery bc it was bad as well. Today the fuse blew and everytime I try to replace it the fuse blows before I can even get it in good. Auto part guy said my battery was the correct one and that my alternator was fine

Disconnect/unplug connector/ all the wires on the alternator and try the fuse again

Hey there boss. I unplugged and disconnected everything. Still blowing the mini 30a fuse everytime I touch the receptacle. Believe it is spot 15 under the hood fuse box

Verify the yellow and white wire to terminal A on the alternator is not shorted directly to ground-use a DVOM

Looking at the diagram. The battery light is working, so the malfunction most likely is coming from the yellow line? Considering it is the only line that runs through the 30a?
