The starter is probley okay, You need to remove the battery cables and clean them up real good. Then check and clean the negative cable where it hooks to the engine.
Clean and check the positive cable where it hooks to the starter.
It sounds like the cable that goes to the alternator needs to be replaced. The cable is bad inside where you can't see it. This would be the positive cable. It is hooked to the starter too.
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
There are several signs that an alternator is going bad. A few signs are dim lights, smell, warning lights, and a dead battery.
The battery light can be on for several reasons. A bad alternator is the top cause in my experience. Have the charging system tested and see what is going on.
Does the Alternator have a power supply back from the battery to excite the alternator? I had the same problem and despite trying several alternators found that a fuse had blown on the circuit bring power back from the battery. Or the bushes in the alternator could be worn out or the diode pack could be shot. Put a volt meter onto the small wire on the alternator and across to the vehicle body you should have battery voltage on this terminal.
There is several things that can cause your battery light to come on. Go to your nearest Advance Auto Parts and have them hook up the battery and alternator tester because your alternator could be bad, or if you have a lot of electrical products such as a powerfull stereo system, gps, DVD player etc., you could be drawing to many amps for you battery and alternator to keep a charge
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.
There could be several causes for the battery charging circuit warning light remaining "ON," and some that come to mind at the moment include: * The battery is seriously undercharged. * The alternator or generator is not working. * There is a defect in the light circuit.
It will run until the battery is too low to support the engine systems, could be 10 minutes or several hours.
Means your alternator is not charging replace alternator It MAY mean that the alternator is not charging. It could also mean one of several other things such as a broken wire. The thing to due is to have the charging circuit checked before replacing a perfectly good alternator.
A lack of charge could be one of several things. A bad battery, bad alternator or bad regulator are the top three suspects.
There are several things that can keep a Chevy Tahoe from starting including the starter being bad, a dead battery, an alternator, or a fuel pump.
The cause could be several factors. one is the battery charged. your startercould be bad or the alternator decharged your batter and your alternator is bad.When you turn your ket you should hear the ignition switch click that means it's fine. if your battery is charged and you turn you key and the lights dim you probably have a bad starter.
