Battery light on and slow turn signals

Postby mikuni » 02 Dec 2006, 12:48

Well basically my battery light came on and my turn signal slowed right down. So I assumed my voltage was droping due to a faulty alternator. I replaced the brushes but its still doing exactly the same thing.

Funny thing is, if I don't rev the car too high the light stays off. If I rev it up to about 2 grand the light will come on and stay on. But not always, sometimes the light comes on as soon as I start the car. But once its on it stays on pretty much, it does flicker a little but doesn't go right off.

Damn I hate electrical problems in cars.

Sounds like a voltage regulator problem mate to be honest.

Oh yeap, where abouts is that? I was thinking that but I haven't had much to do with them in the past, so don't really know what I'm looking for.

If you spotted any electronic looking devices inside the alternator's casing while changing the brushes, that was probably the regulator.

All the NA chevettes (as well as most all NA GM cars) had the regulators integral to the alternator. Not sure about the european models though... :?

:( I have changed the brushes and the reg but its still doing exactly the same thing. I'm on the lookout for another alternator incase the apature or whatever is at fault but I'm beginning to wonder if I'm on the wrong track.

Do you have a electrical tester (voltmeter/ohmmeter)?

You should get close to or zero resistance across the armature Brush surfaces. (with brushes not in contact!)

Also check for resistance on the car's electrical wires... (faulty ground, charging, or field coil wires)

I've made the mistake of purchasing a alternator before checking the electrical connections for corrosion before... still have a new aternator sitting on a shelf for a Suzuki Swift 998cc as a result. "Installed electrical items are non returnable."

Weren't those alternators for Suziki Swifts worth more than the car?

Around $250 if my memory serves right. Part of my problem was delivering pizza in snowstorms with it. It moved just as good as a chevette had, but electrical overload was the issue, finishing off the already corroded connections.

Sold the 5 speed for $400 when I scrapped the car. :lol:
