Re: Alternator brush Posted by Ari [Email] ![]() ![]() In Reply to: Alternator brush, Elmer, Sun, 23 Sep 2001 02:13:58 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The brush is built into the voltage regulator which is bolted onto the back of the alternator. You remove the voltage regulator, and the old brushes come with it. In some models of voltage regulator, you could unsolder the old brushes and solder in new ones. In other models, the brushes aren't replaceable.
My advice would be to buy a new voltage regulator (about $50) and swap it out for the old one. Then you can drag the old one around to autoparts stores to find replacement brushes, if the old one had replaceable brushes. After replacing the brushes, keep the old (repaired) regulator around as a spare.
I have heard that brushes run about $7 to $10, but I have no direct experience. My additude is that getting the regulator in and out is most of the work, so I might as well put a new regulator in. The last thing I want to do is replace the brushes, re-install the regulator, and find out the problem was the regulator electronics.
Good luck!
