3rd Party Car Alarm

Discussion in 'General Motoring' started by Kurt Luchtman, Jul 25, 2005.

  1. I have a 1998 S70 with a Commando Car Alarm that I installed about 3
    years ago. So far the thing has been awsome asside from having to
    replace a few fuses. My new problem is that when I remote start the car
    now the AC/Heat will not come on. No settings have been changed on the
    alarm and looking at the AC when I get in the car, the AC and radio do
    not have any power. However when I turn on the car w/ the key
    everything comes on the way it should. Could this be a problem with the
    alarm not giving enough power to the AC & radio or do I have another
    problem that I am not thinking of?

    There are 2 different circuits that are on when the ignition is in the
    on position. One includes the things that have to be on when the
    starter motor is operation (fuel pump and ignition for example) and the
    other includes of things that don't need to be on (like heaters and
    lights) that are switched off during cranking so more power is available
    to the starter motor. Your remote starter isn't switching this circuit
    on.

  3. Great, so it's back the wiring diagram for me then. I have the wire
    diagram here, can you tell me which one provides power to these units
    so that I am not taking out the whole security system and putting it
    back in. :)

    12V
    Starter
    Ignition
    Second Ignition
    Third Ignition
    Accessory
    Second Accessory

    I am assuming you don't need to know the wire color's.

    There are relays that the ignition switch turns on to provide this
    power. The one for the heater is the "X" supply, which is the
    yellow-violet wire. The ignition switch sends power to this wire by
    connecting it to the red-black wire.
    You also need to to have the alarm connect this red-black wire to the
    blue-yellow (15I) if you want the seat heaters to work. The
    green-yellow (15A) wire powers fuses 2,3 & 4. Please use proper relays,
    one per circuit, and make sure all connections are good and well
    insulated, so you don't fry your car. Personally, I'm not in favour of
    this type of device.
