Battery discharges overnight

1993 Acura Integra

Battery is new and has been re-checked as ok. Can start car multiple times
during the day, but when it is parked for 8+ hours, battery will be
completely dead, no even a ddash light comes on.

Doesn't sound like the alternator to me. Are they any common shorts that
develop on this vehicle?

Thanks.

 

Do you have an aftermarket radio? I used to have a 96 civic and the radio
was causing it, since the installer plugged the power direct to the radio
instead of going thru the ignition switch.

 

Guessing won't fix it. Put a current meter on it and see. A diode could be
shorted in the alternator. In fact anything in the car could be causing
it...

 

I'd go with the meter, after the obvious have been checked, glove box light,
trunk light, bla bla bla, ...........then start disconnecting things till
the draw on the battery is eliminated, ,,,,,,is the belt slipping on the
alternator. .........Is the shop checking the battery doing it correctly,
are they checking the chargeing system?

is the belt slipping on the alternator

 

Hi,
If they're doing it with honesty.
Charging system/battery load test. Fully charged battery with engine
shut should be ~13.2 volts or so.

Don't forget the obvious, how old is the battery?

 

I had a problem with my 91 Accord where the rad fan timer control unit was
mal-functioning causing my rad fan to turn on/off when the car was turned
off. This drained the battering until it was dead. I simply removed my rad
fan fuse as my car is older and soon ready for the car grave. Maybe you have
the same problem??
