Need advice on replacing '89 Pathfinder alternator. Noticed today a loud whining noise with the radio on. Also noticed the volt meter running about 16 to 18 volts when accelerating. Runs around 14 volts at idle. How is the best way to remove the alternator. I have a Hayne's manual but the instructions are not real clear.

Thanks in advance for any help removing this beast.

Take off the skidplate underneath and do it from there. It'd take all day to do from the top. I go through the fenderwell with an extension and socket to access the adjuster bolt.

They're all internal AFAIK and it takes me about 15 minutes to drop the alternator. You must have big hands? ;)

Lame...I swapped my stock alty out for a 110 amp Quest alternator and modified the bracket to fit. Works great!

Disconnect the battery first (negative then positive) before doing any work on the alternator. Once the new alternator is in and connected, reinstall the battery cables (positive then negative).
