Hey all,

I have an autowatch 456 rli alarm, and it has stopped making sound. No chirps and when alarm is activated only lights flash, no siren.

I have contacted autowatch and am told that 95% likely the siren has died...

Basicly does anyone know how I could 'test' the siren out before I potentially waste any money on a siren?

cheers

Well tbh I was thinking about like... Yea snipping them with a crimper on standby with earplugs because I know that should set it off... But I also know if it does go off, im gonna need more than a crimper to shut it up. Maybe manual anyone?

Cutting the wires may not be the best way to test it. The 378001 Digital Back up battery siren will not trigger if the alarm is disarmed, not only that but if you cut through the siren cable you may short it out and cause more damage. Usually if a siren faulty you can trigger the alarm and with the siren in your hand and still wired in, shake it around and hit it with your hand. If it rattles then its RS. If it starts to work when hitting it while the alarm has been triggered and cuts off again, then there may just be broken connection inside the siren or the internal batteries have exploded and the siren is RS. If everything looks ok then check that it has 12v+ and 12V- at the siren end. You can replace the siren with a normal analogue back up battery siren (key switch on it), which you can probably purchase for around $40 but you would need to program the alarm for "negative siren output" instead of digital siren output which it is now.

    • Did you pay with a credit card? I'd be putting a charge back through then finding a new sparky to sort it out. 
    • If you mean the alarm immobiliser; theyre internal to the alarm itself which makes that difficult; I couldnt even see where he put it; its not in the same place as last time; but with all black wiring it might be very challenging to trace  I had someone turn the key for me as I know it only primes for a couple of seconds As my post above; I am getting no voltage to the pump at all; but I am testing continuity of the power line (SB) from the pump plug to the relay fine. As well as the negative from the pump plug to a 12V constant.    Yeah; he blammed the no start on a bad battery; said I needed to get a new battery and it'll start. Turns out the battery drained because the tail lights had been on for half the day during the install (the rubber cushion on the brake switch gave out while he was testing it as I have a picture of the car from that morning with the tail lights off..i've replaced that). The battery was turning over the engine just fine for a long time; but got low since lights were draining it so it was too low to test a start after he finished. I bought a new one on his advice...$250 wasted. My original battery charged up just fine and is healthy.    It was running perfectly fine when I messed up the old alarm (programmed out the remotes). He couldnt start it after removing the old alarm; my assumption is that when he unhooked it; he didnt bridge the circuit back when trying to start it. Its always been perfectly fine. The ECU swap and pump were 2 years ago. It's never missed a beat in that time. 
    • This is a big issue for me without the diff. I just have zero drive from the passenger side when drivers side has no traction. Bec's parents place has a crazy steep driveway with odd camber and I have never been able to get up. My bro-in-law's 130i with an (unknown brand) LSD gets up fine as does their dad's Hiace. My car stays at the bottom. We have other odd camber roads around here as we're elevated a bit and if it's raining I can get totally stuck around some hairpins. 
    • Yeah, I am super excited for this.
    • Was the car running before he touched the car?
