Alternator light

1743 Views 2 Replies 3 Participants Last post by  PickupMan
I have a 1982 Toyota SR-5 long bed 4x4 and my alternator light and brake light have come on and I can not get them to turn off. My volt meter shows that the alt is charging the battery so could I have a loose wire or is there another problem I should look for. I am wondering if any one else has had this problem and what they did to fix it. Thanks for any help.

If the brake and charge lights come on during revving of the engine then it's a sign that the carbon alternator brushes require replacing as this is the mileage for them to wear out. In alternators the brushes wear out on average every 140-170 000 miles where on the dashboard the brake & charge light both come on at the same time. About half of the auto electric shops in your local yellow pages sell carbon alternator brushes and copper solenoid starter contacts for about $5/pair.Another way to verify that the alternator is not charging is while the engine is running bring a metal screwdriver or any metal object near the alternator and if the alternator is working properly then it should act like a magnet and grab the screwdriver.

I had the same problem on my 86 pickup with a 22r in it. check the cable running to the top of the alternator, if you can move it by hand, that was my problem. Some alternators are extremely touchy with the tightness of the connection. If it can be moved by hand, disconnect the positive battery cable, grab a 10mm socket w/extensions and tighten that baby up. don't overtighten it though, just enough to where you start feeling resistance on the socket. Check and make sure none of the cables are coming in cantact with the heat sheild to the manifolds as well.
