alarm draining my battery?

Hey guys, I installed my alarm awhile back fairly new to the whole mobile electronic scene. Anyways, I have everything wired up correctly I believe, the constant 12v is wired up to my ignition etc. I used my multimeter to make sure it's right.

I haven't been driving my car in about two weeks, and the alarm has drained my battery. Car starts fine when jumped, alarm works fine, everything works fine but if I don't drive it within two weeks the battery will die. The battery is also fairly new as well.

What kind of alarm and what kind of car?

The most common mistake is to connect the starter kill relay to constant 12vdc instead of ignition power.

If this isn't your problem then you'll need to use am ammeter and determine how much current the car is using when everything is off (standby current).  You can then isolate circuits until the current draw is below 50mA.

Sounds like what I did.. LOL!! Thank you so much, you've been really helpful! That would explain why my starter kill relay didn't work. I had my alarm armed, and I was still able to start the car up.

Nope, if you had it wired directly you won't be able to start with the system armed! Also it would result in your flat battery when you have the car parked and the alarm armed over extended periods as you did!

I'm sorry but what color is the starter kill wire usually?

I ment on the alarm brain, I have a clifford 50.5x (g35 sedan 03). I read the manual I think it's purple I have to double check it's

Depending on how old your car battery is.. if you did not start your car or charge your battery in two weeks.. the battery may not hold a charge over time. And I am gonna guess it has nothing to do with the alarm. It draws minimal current. Test your battery several hours after the car sits and see what the volt meter reads..if the battery is more than 3 yrs old.. that might be the problem. Just a thought.

"The alarm has drained my car battery" urban myth is as old as "blame the last person who worked on the car"    We STILL don't know what car this is and frankly leaving it standing for two weeks will kill the battery on almost any modern car. The alarm's LED is enough or maybe a stuck or incorrectly wired relay or amp.
Green wire goes to the key side starter wire, purple (violet) to the starter side.

Not familiar with that unit, but if the relay is an onboard one, and the system is arming and disarming normally, then it's highly unlikely the starter kill is connected to a constant instead of an ignition source!

Darren, it's a re-branded 5901 or 5902 I think not a "proper" Clifford but let's not go there.

Really. then it couldn't be connected directly, unless he used an off board relay!

How old is this battery and yet once more what vehicle is this?

I stated in my last post that my car was a 03 G35 Sedan. I'm using a clifford matrix 50.5x

on the 50.5x the ground when armed is the orange wire in the 12 pin harness. it can be used to trigger a starter kill but not the best way on this alarm. the relay satellite harness has a starter kill relay built in. using the large purple(car side) and green(key side). if the entire system is wired correctly, only a faulty alarm brain could cause the battery to drain. my best suggestion is to disconnect power from the alarm for 2 weeks and then try to start the car. if it starts then you most likely have an issue that would best be resolved by having it replaced under warranty. if it still doesnt start after the 2 weeks, you need to have the battery & alternator checked to see where your problem is

OK we have a vehicle with all the latest processors humming away that sits around for two weeks, any one seen the size of the batteries on big BMWs, Jags or Mercedes? There's only going to be one answer here, have the battery and alternator tested first.
