Yes, that would definitely drain the battery.
It could be your alternator is going bad
If you are going to store your vehicle for a long period of time it is a good idea to remove the battery to avoid battery drain.
that light usually means that the battery is going bad or that your alternator isn't charging anymore
If you are out of gas or something and keep cranking the starter then yes sooner or later you are going to drain your battery. Age of the battery is a factor, the older the battery the less time you get. Also the temperature if it is below zero out you get a lot less time.
Typically, a bad or "going bad" alternator.
My guess would be your alternator is going bad. better get it checked out pronto.
It means that the alternator is shot or the battery is shot, you need to get the charging system checked out.
There should be one on the left side bottom of the radiator. There probably isn't going to be one. Maufacturer's started eliminating the drain plug to save on production costs in the late eighties.
no, it would make everything in the car dim because of no charge going to the battery
the voltage regulator in the alternator is going bad it can possibly stick when everything is turn off and drain you battery over night.
There are 3 possibilities: either the battery is going bad, a device is being left on in the car (lights, etc) or an alternator diode is shorted.
