i just installed a pioneer deck in the fc and now my security light and buzzer near the armrest doesnt work? it worked before i installed the deck, so im assuming it may be a fuse that got wrecked. but event then i dont know which one to check. help please.

 

Meter fuse.

 

Sounds stupid, but sometimes if I don' shut my hood all the way, or not hard enough, the car won't arm. Even if the hood is shut, open and close it again... I'm assuming you were in there to disconnect the power on the battery? Most likely a fuse as satch stated though.

 

i checked and my meter fuse was just fine. any other theories?

 

When you say "buzzer," which buzzer are you referencing? The alarm unit is powered by the Meter fuse and the security light gets its voltage from the 7.5 amp "Room" fuse so check that one next (security light gets its ground from the alarm unit and again gets powered up by the Room fuse so it's either the Room fuse or the alarm at fault as far as the security light is concerned).

 

the buzzer letting you know that the security is armed. when you lock your doors
