battery drain help
I have developed a parasitic drain. Folloed the posts here to narrow down the problem circuit. My test light goes out when I pull fuse 11 in the panel to the left of the dash. It is labeled bat/radio/ip oil lvl-life. I pulled the radio and disconnected the wiring. the light is still on. Could the oil level sensor be causing this? No good wiring diag to figure out what else is on the circuit. A fully charged battery lasts about 2 days of sitting before "click, click" An amp gauge between the negative post and cable shows 0.24 amps on a 10A scale. I wouldn't think that would be enough to fully drain the bat in 2 days. Any suggestions? :?: I haven't had to post is a while. That'* good, isn't it :?:

How old is the battery? The .24 amp discharge doesn't sound like a lot, but over a given time period will add up. Figure roughly 1/4 amp discharge per hour, multipy by 24 hrs.= 6 amp/hrs taken out of the battery. Two days worth would be 12 amp/hrs discharge etc. with nothing (ie. alternator) putting amp/hrs. back into the battery. ( if car is sitting dormant) Couple that with cold temperatures & that will kill a battery for sure.

The first time the car sat for 3 days in 0 to 15 degree temps and was completely dead. I checked the battery and it was 5 years on a 6 year battery, so it got replaced. That was 2 weeks ago. Since then, the car has been in 15 to 30 degree weather and a full battery is discharged in about 11/2 to 2 days if not driven. If driven regularly, there is no problem.

Fuse 11 should draw some amps. The manual says this:
Adaptive Lamp monitor = 0.5 - 1.0 mA
HVAC Programmer = 0.5 - 0.75 mA
Gages Cluster = 4.0 - 6.0 mA
Oil level module = 0.1 mA
Radio = 7.0 - 8.5 mA
Amplifier = 1.8 - 3.5 mA
Total = 13.9 to 19.85 mA = 0.02 A max.
0.24 amps is too much.
Also, Fuse 11 goes to the
Front cigar lighter
I/P Compartment Lamp (Make sure you check that one!)
Multi-function chime module
Adaptive Lamp monitor = 0.5 - 1.0 mA
HVAC Programmer = 0.5 - 0.75 mA
Gages Cluster = 4.0 - 6.0 mA
Oil level module = 0.1 mA
Radio = 7.0 - 8.5 mA
Amplifier = 1.8 - 3.5 mA

Man Fuddy, you are a plethora of information. Thanks for all of the info. I was hoping someone would be able to provide a little, but wow! I don't suppose you would want to track down all of these circuits and repair them for me, would you?
I'll get started and see what I can find. Adaptive Light Monitor? I wonder if that would be the $162US part that may be keeping the Twilight Sentinal from working correctly? The lights like to shut off on there own...........while I'm driving.
Thanks again. I'll let everyone now what I find.

If you have a power antenna this might be doing a drain as well. Check the fuse it'* hooked up to. If the antenna is stuck barely up, it'll run all night long at an interval trying to lower.

2002 Oldsmobile Silouette - Parasitic Draw question
I have a 2002 Oldsmobile Silhouette. The battery kept going completely dead. We have it at a AAA Car Care Center for a new battery, then a door module replaced that they said was creating a parasitic draw. We had it towed back in when the battery went dead again. The manager said that the draw on the battery is currently .082 and that is within the range for this vehicle'* specifications.
Can anyone advise me as to whether this is an acceptable draw for this vehicle?
I keep hearing .05 (50 milliamps) or less is the standard parasitic draw. Would .082 make a difference in battery performance over a .05 draw?
