Disconnect alarm


Yes,is possible.Because it'son when sitting still/not driving.Along with a lot of other things,like the cronemeter/clock.This stuff will drain a battery after sitting for a good while.Slowly,but still a drain.Most likely the battery has been in use for a good while and may need replaced,but if you don't wanna replace the battery,just disconnect the alarm system or pull the fuse from the panel to deactivate it.

1999 oldsmobile aurora headlights go off in middle of night and sometomes alarm


It sounds like you have a malfunctioning alarm system. If it is an aftermarket system, you should simply turn it off. If it is a factory alarm it would really be best to take this to a dealer. In the mean time, to prevent battery drain, you can disconnect the black battery terminal at night when you park the car.

My alternater and battery test good on my 01 kia spectra.But, After putting the fully charged battery in my car, it slowlky died in on ly a few blocks drive?


Connect an ammeter in series with the battery positive terminal and battery positive lead. With ALL systems off, including alarm, door lights etc and with doors closed you should have a reading of only 0.03 amps.I'm guessing that yours is higher as it sounds like you have a parasitic voltage drain.If indeed it is higher, then disconnect any alarm system first and check your amps again. Every time you disconnect something, go back and check your amps.Once you get your amp drain back to normal, then you have managed to disconnect the system responsible for the high current drain.
The most likely candidates are always the alarm system, then stereo, then GPS tracker. After that you will have to start pulling more fuses, one by one and letting the vehicle rest for a few minutes after each thing is disconnected before taking a reading.
BTW, if it is the alarm which is drawing a high amp drain, then it is more often than not the alarm siren back up battery which has failed.
Good luck.

How do I disable the stock alarm on my 2001 Oldsmobile Aurora 4.0


Maybe you are in valet mode. This will drain your battery.

I believe that the alarm system in the car is draining the battery also causing the car not to start.....I want to disconnect the alarm system or disarm it but cannot locate the valet switch...my friend...


This sounds like a factory alarm, so it is unlikely that it is draining the battery. Much more common is alternator diodes. diagnosis is pretty easy for a shop, consider using one for this issue.

1998 Jeep power drains battery over night


Before you disable your alarm try this, disconnect the alternator field plug over night, check battery voltage at the battery before you disconnect the plug then disconnect and leave alone over night, make sure you have at least 12 volts when you disconnect the alt.
Recheck battery voltage in the morning before you reconnect the field plug...

I suspect you may have a leaking diode in your alternator's internal regulator, have seen it many times on your model... Certainly worth a try. Let me know how it turns out....

Car wont start


Sounds like you have a shorted wire causing a drain. I recommend disconnecting the alarm all together which should stop the short so battery can remain fully charged.

97 vw jetta w/aftr mkt. alarm drains battery and disarms on own?


My friend you are faced with a catch 22 problem. The first thing I would like to know is, who installed the alarm system? Did you do it or was it professionally installed. If it wwas professionally installed I would go right back there and discuss the problem with them. It very well could be a defective unit. If you did not have it installed professionally I would disconnect the alarm and see if your battery still get's drained.If so, then the alarm is not the culprit, and you have some hunting to do. If not then you have some testing to do.Next what type of alarm is it? Try to google it. You may be able to find a trouble shooting guide to assist you. I know that you said you just replaced the battery, but the alarm very well may not be the culprit. It could be many other things as a loose fanbelt, bad diodes in your alternator, or some other componet draining your battery.

Battery drain


Best bet is to disconnect the clock and disable the alarm and see if you still have a drain. If you do, it's likely that it's something inside the computer (although that seems far-fetched). Chances are there are more components than that in the suspect circuit. However, that being said, I'd suspect the alarm system - the ECU doesn't really draw power with the car off, per se, and the clock is a minimal drain. Something shorting out in the alarm however, will likely drain your battery quickly. I have seen faulty sensors added as part of an alarm system cause battery drains in the past.
