In my continuing saga of battery drain; I've gotten conflicting information (not strange really; considering all the places I've sought info)
Here's what I know:
I have a drain, when adding up the mA's across fuses; about a 170ma drain.
If Idrive the car, then stop; the battery has a voltage of just about 12.5-12.8 volts
If I put the battery on a charger, after driving, it jumps to 9 amps and I measure 14.8 volts at the battery..
Pulling the charger off; I can watch the volts drop slowly, but steadily slowing down around 12.5. This happens regardless of the battery being connected to the car or not.
If I let the car "sit" for 2 days; the battery will not be strong enough to start the car.
the battery is relatively new. (less than 4 months old)
Theories/opinions.
Max battery drain should be no more than 50ma -- I haven't been able to confirm this anywhere.
at 200ma; the battery should not be dead in 2 days
Possibly the alternator is bad & if the diode is blown; it is draining the battery when teh car is off.
The battery is bad and not holding a charge.
Questions:
Could the alternator really drain the battery? If so; is there an easy way to disconnect the alternator? one of the two bolts on teh alternator is 'blocked' by the oil filter.
Could a bad alternator have killed the battery?
What is a reasonable battery drain (range) to expect from all the computers & whatnots?
Based on the rapid decline of voltage held in teh battery when disconnected; the battery is probably shot, correct?
Thanks all!
