Its not charging.
It could be a bad battery.
Yes, if the relay was stuck it would drain the battery.
Because if you reversed the polarity at the battery it would blow the fuse through which current flows to the drain.
Well i would suggest connecting the battery...
A car battery in any car would drain due to a short in the electrical system.
A raidator in need of a flush will not cause a battery drain.
For a battery to "Drain" you MUST have a short somewhere or the "Glovebox" or "Trunk" light is staying on etc. etc. Battery's don't just "Drain" on there own ;-) TommyTrouble
No. The power to illuminate the Daytime Running Lights (DRL's) is supplied by the alternator, and does not have to be supplied by the battery. Once a vehicle is started and the engine is running you could remove the battery from the car entirely and everything requiring current would still operate.
A short in the wiring.
Yes, that would definitely drain the battery.
Yes, but only when you have the starter engaged
Happened to my 97. The alternator went out. Had to replace it and get a new battery. No problems since.
