with everything off unhook the negative terminal an place a voltmeter between the battery and the cable if the needle comes up you have a draw. start pulling fuses until the needle drops when it does you've found your current draw
usually means that the alternator is not charging. So the battery is being drained.
the positive wire that recharges the battery after being drained from the starter
dead cell in the battery or something is on that is pulling power from the battery.
have you checked the alternator??? that's the first thing that comes to my mind if your battery is being drained
Your starter is incapable of being drained. It is an electric motor. However a bad starter can drain your battery
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
It's most probably the alternator. It's not putting any charge back in the battery. Can also be a dead cell in the battery or something is on pulling power from the battery.
The battery indicator lamp illuminating usually means that the battery is not receiving or accepting a charge from the alternator and is being drained past an unsatisfactory state of charge.
It's easy to distinguish if your car has a damage alternator or battery. The first thing you do is to start your car using your old battery then, once the engine is running then remove the cable from your battery, if the car still running that means the alternator is still charging but is it enough? so you have to measure the current that is being generated by the alternator using a multi tester. If the reading from the tester can reach 13 to 14 volts then your alternator is still good. If not then the carbon brush of the alternator might need to be replace or the IC. If your car battery is already leaking then it possible that the plates are already damage, or if you have tried to charge your battery but the power is easily drained then it needs to be replace. i hope this can help ......... deep
The ABS light is likely coming on because the voltage being put out by your battery isn't enough to satisfy the requirements of the ABS system. It could be either the battery or the alternator. Put a load test on the battery and make sure that's operating within the requirements, and put a volt meter on the battery after starting the car to see the alternator recharging the battery. I've seen it both ways, alternator is bad and need a new one, or the battery is bad and need a new one.
Most likely cable running from stud on top of alternator to battery terminal is corroded or broken.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
