Re: OEM Alarm System draining battery
The head lights and tail lights are tied into the alarm. When you hit either the lock or unlock button any thing tied into the light wiring will be triggered as well. Just an example; if you added additional lights to the car and spliced them into your head light wires, these lights would go on with your head lights, or if you lock/unlock the car the lights these lights will flash as well as with the head lights.
The light flashing are just parking lights, when you step on the brake there should be more light, to distinguish between the parking/running lights and the brake lights (think of when you are behind a car at night and the change in light brightness when the car ahead brakes).
Don't quote me but I believe the amperage draw for the alarm is ~0.25-0.5 A.
When you say you attached "...positive...negative..." what were the leads attached to? The alarm always has some power to it, and if you test a ground or positive of the car and the power or ground for the alarm you'll get a light. Pulling the fuse cuts the power before the alarm so the light should go out.
It is possible that having the car sit weeks at a time will drain the battery, no matter what, but I do no now how long the battery should last when the car just sits.
If your daughter is waiting and the car doesn't need to be moved too much you can just pull the alarm fuse until the car is ready to be driven, however the key fob won't work while the fuse is removed so you will have to use the key. Of course you also have to be certain it really is the alarm causing problems.
