Where is the loose wire? What part of the alarm do U want to test? Is it a factory alarm or aftermarket one?
The siren has a wire loose it says battery back up siren 20w 1 tone I just bought it without reg and curious if the guy is gonna try steal it back??
if he was going to steal the car he would have kept a spare key and remote your question is still not clear, do you want to know what the wire is or how to check if alarm works and we still need to know what sort of aftermarket alarm it is
It doesn't say what it is there's just the siren thingy on the passenger side with a three wire plug hanging out? I just want to check if it works without having to smash. My window
Wind your window down, lock the car, unlock the door by hand from the outside then open the door and im pretty sure that should set the alarm off.
asxVTx said lock your car with windows down wait 5 minutes (most alarms have a timer before they arm) then reach in window and unlock door and open- alarm should sound then reset alarm start car, then turn off and lock car again wait 5 minutes, undo 2 screws holding remote to key then just using key reach in window and try to start- alarm should sound
