Can anyone help me with my alarm please. I have everything hooked up right but the orange wire that is supposed to be (-)500ma ground when armed output doesnt have any ground when the alarm is armed. And my alarm also doesnt get triggered by any sensors i plug into it. i tried plugging in the sensors individually, and the sensor goes off but doesnt trigger the alarm.

You'll have to wait for "I am an Idiot" to come across this as I believe he has the cyrstal ball that will have to be used to determine what kind of alarm you have and what kind of car it was installed in.

The relay's terminal 85. Im using the relay to kill the fuel pump instead of the starter

Not to seem obvious, but have you checked that GWA output with a meter?

Bet the alarm itself hasn't been grounded properly, check your voltage with a DMM across the supply feed (red?) and the ground. Of course it could be an internal fault, the non-working sensors are a good clue, check t&t's last post.

Yes i checked it with a meter, i put one end of the meter to the car's ground and the other to the GWA wire. The setting i used on the volt meter was the one that when you put the two ends together it makes the beeping sound.
and i've checked the voltage, and it shows like 12.4v
In fact, my friend has the same alarm installed in his car but the relay and the sensors are not hooked up. i checked his orange wire and its just like mine, it doesnt have any ground when armed nor the sensors work.
I dont know what to think anymore. its just so weird

Does your unit come with a manual?
