Hi im Reggie thanks for using JustAnswer. Put my years of experience and training to work for you
Hi Do you have battery voltage on the big wire that hooks up to the alternator?
the pcm controls the regulator do you have a scan tool to check for codes
The fuse link that you speak of is in line on the big wire that hooks to the back of the alternator this can be checked by verifying that this wire has battery voltage when it is un hooked from the alternator
Do you have a voltmeter or test light
Okay if you go out to the alternator and disconnect the big wire does it have voltage while it is unhooked from the alternator
