Positive Systems:

Very similar to the negative system, except that the vehicle's clutch relay is trigger by

12 V, instead of a negative signal. In a Positive system, when the clutch is pressed; a

positive (12 V) signal is sent to the relay, the relay energizes, when the Key is turned to

the

position the 12 V from the start wire is allowed to pass through the relay and to

START

starter motor. One of the wires at the clutch will test as 12 V, this is the supply wire. The

relay's positive trigger wire will only show positive when the pedal is pressed (some

vehicle's also require the Ignition system to be powered). To confirm you have Positive

system, hot wire the positive trigger wire by jumping it to a 12 V source with your fused

test jumper. You should now be able to turn the key to the

start motor, without pressing in the clutch pedal. A relay is needed to send 12 V to the

trigger wire from the Remote Car Starter during start attempts.

Note on N/C systems:

There are different types of this system used by various vehicle manufactures, the following is used

to illustrate how these systems work in general.

Normally Closed (N/C) Systems:

In the previous two examples, the clutch was bypassed by engaging the clutch relay. In

an N/C system, a relay is also used to interrupt the starter wire. In order to bypass an

N/C Clutch, one must prevent the Clutch relay from engaging.

If the pedal is not pressed, when the Ignition Key is turned to the

energizes and interrupts the start wire. If the pedal is pressed, when the Ignition Key is

turned to the

START

Starter Motor.

In an N/C system, the supply wire is connected to the trigger wire of the relay at rest

(Pedal not pressed). When the Pedal is pressed, the connection is broken between the

supply wire and the trigger wire of the relay (disengaging the relay). To verify that you

have a N/C system disconnect the clutch switch, and the vehicle should start without the

clutch pedal being pressed. When you test the trigger wire with your logic probe, the

trigger wire will test as 12 V or negative when the pedal is not pressed, it should read as

an open circuit ( or Float) when the pedal is pressed.

Please note:

Your probe may also show feed back from the other

end of the circuit. The Polarity of the Trigger wire

does not matter in this system: all you need to do in

order to bypass it is to use a relay to interrupt this

wire during remote starts.
