1989 Trooper

After I've installed the remote starter in a Isuzu I  have the following problems

when i try to connect the wire harness in to the module the sieren goes on and there is no way to shut it off unless i cut the ground of the siren I've tried with the  remote control

Test the output of the siren wire and see if it is a constant output. If it is, then you have a bad CPU.

thank's Jeff I'LL try that way

thank u

you right Jeff

the cpu was bad so we get another one, It seem to work fine

but the only problem that I had is the starte kill relay ,when I try to start the car with the remote it doesn't the only way is jumping a wire from 87a to 30 of the relay

this is the way i hooked up

• 85: Switched 12 volts from Ignition #1
• 87: NOT USED
• 86: Starter disable wire form alarm
• 30: Motor side of the Starter wire
• 87a: Keyside of starter wire
• also there is a diode between 86  and 85( the stripe towards  85

Try this and post your results:

• 86 : Switched 12 volts from Ignition #1
• 85 : Starter disable wire form alarm
• 87a: Keyside of starter wire
• 30 : Motor side of the Starter wire
