I Need Your Help Guys,

i have a 97 honda civic dx with after market power door locks. they were working perfectly fine until one day. i was testing for ground when i heard a spark. then my alarm stopped working. i checked and saw that i blew a fuse in the alarm. i replaced the fuse and the alarm works fine but the power locks don't work now. What can it be??? i thought maybe it can be a relay but when i press the alarm and touch the 2 relays i see they do click when i arm the alarm but they don't click when i disarm, is this normal??? Any help is appreciated.

thanks

did you get power for the 2 relays with 1 wire or 2....? (constant 12 volts) and is the 12v sorce wire for the relays fused? If you used 2 wires, one for each relay...check the unlock "fuse" Check the NEG(-) output from the brain that triggers the relay as well.

both relays go into one 12v source wire and it is fused. i check the fuse and it is fine. when you say check the NEG output from brain, you mean the alarm brain right??? just making sure.

thanks for the reply

You said in your first post that the relays don't click when you disarm....is this the case or not? They should click on both lock and unlock, if they dont its one of 2 things....the input FROM the brain (the neg trigger) OR the constant 12volts supplied to the coil of the relay. OR you got a bad relay....wich I doubt.

Use your meter on the outputs from the brain......no guesswork.
