Alarm sensing a door open.

I can get to the brain, but it'll be a pita.

While it's gonna **** that does sound like the best option for a definitive answer.

Yeah I would check the connection of the alarm to the factory wiring. Check voltage at factory wire (which sounds like you have already done, just being thorough) check after the connection on the alarm side and check at the brain. We can go from there.

Deal. I'll be back in hopefully not too long.

There is voltage all the way to the brain. I even took the cover off and tested after the connector.

Nothing looks burnt though...

Good thing it's got a liftime waranty.

Put the door trigger to a constant 12v and arm the system. This will eliminate the fact that a voltage under 12v is causing the alarm to false.

I am aware that it has been working the whole time but sometimes electronics act funny after awhile. Either way it sounds like its a bad unit but if it doesnt false with a full 12v there could also be another problem.

There was a pin switch on the board labeled 8V I'm not sure I want to put 12 on it if it's only meant for 8. Let me scroll through the manual again.

A door trigger should be able to hold 12v no matter what as a lot of cars still have 12v door triggers but I see what you are saying.

Do you have the domelight wire (black/white on alarm) hooked up to anything?

Another thing I noticed was there is a domelight delay in option 10. You could try turning that on. I have seen cases where a domelight delay was programmed and then all of a sudden the unit reverted back to original programming.

Not necessarily the case but you never know. I am not all that familiar with the caprices as far as domelight delay so maybe Noah could provide a better answer on that.

Mine has a stock domelight delay.

I called the company I bought it from to ask if they had any steps they'd like me to take to check it before I ask for them to swap it under warranty.

Let me know if they have any ideas.

sounds like your doing it good. it is probly something stupid. how old is the unit?

 

[UndercoverPunk 5,000+ posts]

not even a year and a half.

check the ground or grounds? or relays

The door trigger is negative, it should rest at ground when open...

Check for continuity with ground, also... did we do anything for the xtra trigger of the back glass... I think we did?

If that is tied in with the door trigger that could be the problem. There could also be a separate trigger that it is tied into off the alarm and thus not being the problem. Tough to tell without seeing how the alarm is installed.
