Battery and Alternator question
Hey all,
Driving in to work today, for the first time since I've owned my Saturn (SL2, 98, bought used in 2001) my battery indicator light came on. Now, I've heard and read in the past about the problems that Saturns have with alternators, and if you get your alternator changed you should get the battery changed at the same time, but my question is: is this true in reverse?. Can I just head down to Canadian Tire and get a new batt and drop it in myself?, or are there tests or verifications that I should do first to find out if my alternator needs to be changed as well? TIA!!! Wurm |
The 'battery indicator' is really a charging system indicator and comes on
when the ignition is on but the alternator is not putting out any juice. I'd have a charging system diagnostic run first before replacing anything.

While I was driving in, as soon as I noticed it I turned off my lights and the indicator went away for a few moments before coming back on. I then turned off my stereo system and once again the indicator dissapeared for a few minutes only to eventually come back. How worried should I be right now about this?, should I get this checked immediately or should I be able to wait till early next week (got a week off) to bring the car in? Thanks again! Wurm |
You have about 80km to go, or 40 at night. I'd leave the radio and climate
controls off. If you have a battery charger, you can limp along driving less than the above distance and recharging it overnight. Either way, get it in soon for a new alternator. It aint good for the battery to drain that much repeatedly.

You should be VERY worried about making it anywhere. The fact that the light came on, then went off when you turned the lights off, then turned on a few minutes later, then back off when you turend the stereo off, then came back on......that means the alternator isn't charging, you're running only on the battery - and the battery is almost dead! It will rapidly decline until the light comes on every time you hit the brake pedal(current draw from brake lights). Shortly after the gauges will all go to zero. Soon after that you won't be driving the car. |

You're on borrowed time. I'm surprised the car still starts in the
morning. Must be a REAL good battery. I've put 3 sets of brushes in my original 92 alternator (still installed, with 270,000 miles on it). Thy're carbon and wear down....then the light! Hardest thing is getting the alternator off the car.... Split the alternator case, install new brushes (requires soldering unless I'm confusing it with the Nippondenso I did for my buddy last month -CRS), PIN the brushes with a straightened paper clip so they are fully recessed, slap the case back together, pull the pins, reinstall alternator and you're good for another 80-100k. Lots of auto parts stores carry the brushes, though you may need to carry in the old ones to compare. Or just buy a new alternator.....but that's no fun! As far as your battery goes, have it tested. Good is good. No reason to change both if the just alternator is bad. That kind of advise comes from mechanics padding the bill for profit. |
