I'm still ordering the brushes & holder from Jacque, & will fart with my other alternator later. Maybe it will come up as a cheap sale here....~


Just looked on page 1 of the thread...it was a 1 year warranty. If I'm not mistaken, I paid around $13 for shipping..

Been very happy with this purchase! I didn't expect much but was pleasantly surprised.

'Ol Red has 277, 000 miles on her now. My plan is to make it to half a million miles~

just make sure you upgrade your alternator to battery cable.

I'm going to put a premium 4 ga wire on it straight to the battery. What did you do to the original wire ? Tape it off or just pull the fuse or something?

Seems like to me you would do away with it because wouldn't it still draw current through it?

Leave the stock wire hooked up. Electricity will flow through the path of least resistance so you don't have to worry about it burning up.

im not an expert on wiring but if I put a 150 amp fuse on the alternator 4 ga wire and the stock wire is fused for 80 amps wouldn't that make margin for the truck to pull 230 amps possibly burning up the alternator? any ideas here and is it necessary to leave the original wire hooked up?

The fuse is not to protect the alternator, it is to protect the wiring incase of a short circuit so it doesn't burn up. When under full load, the alternator can only produce what it is capable of, not any higher.
