Hi there,

To be clear, there isn't any power to the alternator from the battery and the fuse box doesn't have power but the vehicle will start?

What color wires are you checking for power on the alternator and how are you checking for power?

Customer: replied 1 year ago.
Can you just call me
Expert:  Mike V. replied 1 year ago.

Sorry, I am unable to call at this time. I am going to open this up to the other experts for you.

Please do not reply or it will lock it to me.

Expert:  Mike S. replied 1 year ago.

Check or replace the fuse K in the fuse block. If you have no voltage at the alternator larger wires, B and S white wires, then it appears the fusible link between the alternator and the battery is burnt up. It should be the black fusible link.
