something is causing a drain on the battery when switch is turned off
Yes, alternators are designed to maintain the battery, or recharge a battery that has been slightly discharged from starting the car. When the alternator is used to recharge a dead battery, it causes the alternator work harder and longer than it is designed for, causing it to overheat, thus causing damage to the alternator. A battery charger should be used instead. They are designed for charging dead batteries. After the battery is charged, let the alternator maintain the charge.
The battery light indicates that the battery is not receiving a charging current. You may have a bad alternator or a broken drive belt (if you have a broken belt you'll have overheating and power steering problems too, though).
The sunroof on a Chevy Cavalier can often be repaired by replacing the outer seal. This prevents rain from leaking into the vehicle and causing additional problems.
weak or faulty battery, faulty alternator (or slipping alternator belt causing battery not to charge) or faulty starter motor
Some possibilities: Cable is loose Alternator is faulty Some other electrical problem is causing an excessive drain. ---------------------- Also check the Fuse or Fusible Link. ----------------------- if new alternator: ck. mounting bolts for tightness & wiring. battery self maintenance? Alt. have intregal regulator? if not, should replace when replacing alt.
An auto battery could be leaking for a couple of reasons. The alternator could be overcharging the battery causing the leakage. Or the battery itself could have a short or other internal problem causing it to leak when charging.
Several potential reasons that your battery is not charging. It could be that your battery is too old and must be replaced. Alternatively, the electrolyte in your battery is low and that you have damaged your plates by not replacing the lost fluid with distilled water. Thus, you may have to replace your battery. Or, as you suggest, it could be a defective alternator (actually voltage regulator in the alternator). However, first you should check the belt your alternator runs off. If may be loose, causing the alternator not to charge the battery. Old belts develop multiple microcracks that will loosen the belt tension. Have you replaced your alternator belt since you purchased the vehicle (about every 50,000 miles)? If your belt is tight, it could be that your alternator is bad. Brake light could be related to alternator issue, or you have a separate problem with the brake fluid sensor. Remember to check your brake fluid at least monthly. Hope this helps.
It can happen. The bearings on the alternator of my Silverado did that once, and it ended up causing the vehicle to shut down. the alternator on your car charges the battery which in turn runs the electrical supply to the car. if your alternator is damaged the battery will deliver power to the eletrical system until it no longer can and the car will stop running.if i were you i would replace the alternator,recharge the battery if it is still good and then happy motoring.
Alternator Belt has snapped, causing you alternator to stop charging causing you battery light to come on, but this belt also runs your power steering pump which if that's not working your steering will become heavy
All that would be left would be a short in the wiring to the alternator.
If its an old battery the cells could be dried up, meaning there is not enough battery acid in it, or if you leave your lights on, or a bad alternator could be causing the battery to not charge while the car is running.
