either the alternator is dischargeing the battery or it is going flat just because its not getting re charged
no a egr valve would not make a dead battery. a bad alternator or maybe a bad connection post to battery would make it die ,
Spark plugs don't smoke. A bad alternator would cause a dead battery.
dead cell in the battery or something is on pulling power from the battery.
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
Dead battery, car will not start
Either your battery is dead, or your alternator has failed.
Dead Battery. Are you sure your battery can maintain or hold a charge?
Not likely, but running the engine with a dead battery can damage some alternators. Always fully charge the battery when installing an alternator.
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
Your charging system has failed, probably the alternator.
It won't. Look for a light that is on or a stuck relay. Also a dead cell in the battery will cause it to run down overnight.
if the battery is dead, there will be no ignition lights etc when u turn the key your headlights would be very dim if on at all. the alternator only works when engine is running, so if alternator is dead it will not charge the battery most auto stores will check both battery and alternator for free if you remove from car and take them to the store
