Immobiliser Wiring
Hey people,
Hit a snag installing my alarm. The immobiliser circuit is only rated at 18 amps but judging by the thickness of the wire coming from the ignition switch its handling a lot more than that. What can I do? Don't want to burn out the alarm wiring but equally really need this circuit.
Does anyone know what the current draw from the ignition switch is on the yellow crank wire and if up at 200 amps which is usual for a loaded crank, how can I get around this?
Many thanks
Rich

200 amps do not pass thru your ignition switch.
The ignition switch activates a solenoid for that type of current.
You did not state the make and model of the alarm system therefore this info is generic.
Due to the thin wiring on the immobilizer, those wirers are intended to go to a relay, perhaps not supplied with the kit.
Then the high current side of the relay can be used to disable any circuit in the car.

Re: Immobiliser Wiring
Sorry for the late reply, really appreciate the information. I agree it needs to go through a relay, would you know how to wire it?
The alarm is a SIGMA S30

Connect 86 to ground.
Connect 85 to the output wire from the immobilizer.
Break a connection from the device you want to turn off (fuel pump, solenoid, etc).
Connect those wires to 30 and 87.
That’s all there is to it.
