Not sure if this is true for all alarms, but the alarm wont trip the immobiliser unless it has been triggered (alarm sounding, lights flashing etc...) If it has fully tripped and it still lets you start the car, grab a multimeter and check the signal to the immobilising relay, earth and connections to the ignition (or whatever it is stopping, fuel pump mabey) if there is a signal to the relay, but it is not activating (you should be able to hear a soft click) grab a new one, jaycar would have one under 10 bucks, good luck

im guessing u have blown the fuses or something with your indicators.

Try changing the fuses on the wires of your alarm system. Do your indicators work?
