My alarm is killing my battery I believe. Should it be on a 12v constant source? It is wired directly to my battery. Is this the way that it is suppose to be wired? I really need advice ASAP because my car is in the shop and need to know what the fuck to do.. I'm getting all this shit done like new alternator and what not and I hate to spend the money if I really dont have to and the real problem may be the alarm.

yes it should be on a constant connection. If it wasn't it wouldn't work when you turned off your car.

The only way it's killing your battery is if there's a bad ground or if your alarm isn't working properly.

even then tho, an alarm dosent draw enough power to drain your battery, id be checking for other things

I have no idea how to check for this stuff. And the alarm was not proffesionally installed, so I cant take it anywhere and have warranty on it. The other thing is, if it isnt started everyday, it goes dead. Does this sound like it should be happening? What is the longest these things should be able to sit without the battery dieing?

Thanks In Advance

Hmmm.. interesting... sounds like mine was. I have a yellow top optima battery and a Viper 790 two way alarm. It was installed professionally (if you call it that by assholes that fuckes with my audio) but anyway... when I left the car armed for 2 or more days, the yellow top would go completely dead, absolutly no juice.
The only thing that I did was not keep the alarm armed for short periods of time or take it for a short drive. This was just before it snowed, when it was cold.
I dont have much else for a suggestion because the engine got pulled out a month later, and the alarm is coming out because i fucking hate the thing. But I may put it in my Maxima...
Best advice is to keep it unarmed for the period of time and see what happens. Maybe it isnt even your alarm, maybe its your battery??? Do some trial and error tests and see what happens.

That's weird. I'd run up to AutoZone and have them use a battery tester on your battery, just in case. A way you can check to see if it's your alarm draining the just is, unplug everything else from the positive terminal except your alarm. Then you can check the battery's voltage w/ a multimeter in the morning. I would say it is probably not your alarm, but it certainly could be.

I don't know what kind of alternator im getting. I guess whatever my mechanic puts in... probably just a replacement 90 amp alternator. I'll let you kno tho crazyeclipse. I really hope that all this gets sorted out by my mechanic.

Don't you have a system in your car? If so, check the remote lead going to your amp. We used to have this problem when I worked at Circuit Shitty. MTX amplifiers would store a charge due to build in capacitors then when the car was shut off that charge would lead back across the remote lead and ground through the radio. In turn the amp would think it was getting a remote turn on and maintain it's power. So even when the car was shut off the amp was draining power from the battery.

If that's the case you have to put a diode in line with your remote turn on wire. That way 12v can flow to the amp, but not from the amp on that line.

Well thanks for the info for future reference. But I do not have a system in my car rite now
