clifford supernova 2, possible need of reset

Just to clarify, that there is no response when the battery is disconnected, correct. The other possibility is that here is a battery backup for the alarm or a battery backup siren. Unplug the alarm brain to reset it with a backup battery. If the vehicle has a Clifford backup siren with it's own internal battery, there is a key switch on the siren to shut it off.sparky

Hey sparkie: I don't think the alarm horn has a battery but I can check. The odd thing is that the alarm turns on when the alarm is just armed and it stops sounding when the alarm is triggered. It is just working backwards. I might have to disconnect every wire to see if there is a sensor doing this. The grounds are ok. Could a certain car battery do this? I have a big battery that is for an expedition hooked up to the car while I work on it.

As long as the battery is at 12 volts it will work to test the system. It is possible that one of the alarm triggers is active, but the alarm should ignore that input and alert you with some chirps that it senses an active trigger upon arming. Make sure that you use a digital volt meter to verify the grounds are good.sparky

Thanks Sparkie: Hey can I disconnect everything except power and ground and the unit arm and disarm? I already know that there is some kind of wiring problem because if I move the wires around the unit loses power so I have to check every wire anyway. If the unit still acts crazy with everything disconnected I guess that would mean that either the unit is bad or something is up with the horn.
