I have a Viper 800 and has worked without probs for nearly a year. Recently it started tripping out - full out siren, no warning. I've localized the problem to my starter kill. Basically the relay goes on and off for no apparent reason. 85 and 86 is connected to the orange (neg when armed) and yellow (ign). I took the relay off and the alarm still went off. So I thought the car's ignition wire might be pulsing a bit and put a switch to disconnect the ignition wire to the alarm when I arm it. Unfortunately the alarm still went off.

Is it possible that the orange wire is causing some issues? I notice that it reads 12v if no relay is plugged in. It drops to 0v when a relay is connected and then reads ground when armed. With the yellow disconnected, I still noticed that the relay flips on and off somehow.

Any ideas as to what is going on here? I need to get this fixed before I start installing my system. Thanks!

after you disarm your alarm look at the led and count how many times it flashes
and your manual will tell you which output was triggered

you mean which input was triggered [img]tongue.gif[/img]

Check your ground. Make sure it goes to the A-pillar, or other good steel and not a dash bracket.
The relay can't be tripping unless there is 12 volts on the ignition wire. Maybe you have a short somewhere that's pulsing the ignition. The diagnostics should tell you that the ign zone is triggering if that is the case...perhaps a bad ignition switch.
With a test light on the ign wire, wiggle the ign harness, and see if the light flashes.

Oh...just re-read your post...sounds like a short in the relay harness, or the relay (a long shot, but it does happen occassionally).
