It would appear that steps need to be taken to determine the current draw . it can not unless there is a circuit for it to do so . Disconnect the earth strap from the battery and insert an amp meter in the circuit . IF there is a circuit for the current you will read that current and that will point to what unit is capable of using that current with out serious effect. Low current (up to 3amps ) indicates lights so check boot light still on-glove box light on- interior light on-head light module faulty etc.; Higher draw then look for ECM working when it should be off--sensors operating from shorts __HO2s sensor ABS unit operating. Starter motors I would discount because if the solenoid was operating the starter would be spinning the motor. Check that the audio systems are not operational with out making noise .Units I would be checking would be automatic units that draw through a relay and a check for this would be to watch the amp meter for a change as each power wire to the relay/s was removed and re installed . IF you find a relay that causes a variance I would replace that module and recheck the current draw.

You may have internal engine damage . broken cam or can.. try to turn the engine manually with a wrench to see if there is any problem while rotate it. In the cold weather when you start engine especially been sitting for too long, engine part need to be lubricated fast otherwise damage it will occur. check and smell the engine oil for strange condition

Check or have the battery's state of charge tested with a voltmeter. If the battery is low on charge, have it charged up. If all connections on battery and starter are clean and tight,, car should start. If you get it started and the alternator/battery light stays on with car running, there is a charging system malfunction. Have the alternator tested, in that case.

Rather then guessing have the vehicle checked for DTC'S - diagnostic trouble codes in the air bag control module .

this could be moisture going into the starter motor, and freezes over night, making a shortcut to the starter. My advice, change your starter and your problem should be fixed.

Did the battery go bad or down? Batteries fail if their overcharged, not charged, or dragged down from sitting with a draw on them. The altenater may not work correctly as a fuse may be blown. The big power wire on the back of the altenater is hot all the time the battery is connected. Make sure that it is. The plug that plugs into the altenator one wire hot all the time and the other is on with the key if itdoes'nt do that your on the serch to do that. with a volt OHM meter you can tell if it's charging 14.5 volts running and 12.6 volts sitting with the key off. if the battery is below 10 volts the altanator may be a good one but it's smart enough to not to try to charge a dead battery so it won't turn on. The liklyhood of the battery being bad even with it new is possible so don't rule that out.

a battery replacement is common to replace after a alternator replacement because you jump your batter a few times unti lyou find out your alternator is dead after that many jumps the battery will be shot

Hi and welcome to FixYa,

Initially and not knowing if the battery is new, possibilities are:

• one or more cells of the battery is weak, would therefore require replacement (most likely);
• one or more of the diodes in the alternator has an electrical leak, and therefore would require check, repair or replacement (just a possibility).

Good luck and Thank you for using FixYa. Happy Holidays.
