Hey everybody I have lojack and an Automate Model 1 system on my 97 mustang cobra. I'm wondering why my chirp hasn't been working upon locking/arming and unlocking/disarming. Also the siren doesn't sound if I kick the tires to get the alarm to go off. I know it's going off because the lights are flashing though lol. I checked power and ground at the siren. I have 2V when I hit lock and 2V with I hit unlock. The ground is good. Anybody know how much power I'm supossed to have? Also if it is enough power, does anyone know where I can get a replacement siren for a good price? Thanks!
