Glow-plug

input

This positive input will monitor the Glow Plug Light in Diesel Mode: it will

wait until the Glow Plug Light goes out to crank the Engine. Connect to

the side of the Glow Plug Light that becomes positive when the Light is

on.

Note: In Diesel Mode there is an 18-sec. crank timing delay (or

approximately 25-sec. if the run time is set to 30 min.): if the Glow Plug

Light is still on after the delay expires, the module will proceed to start

the Engine.

(Also known as the “wait-to-start light”.) The purpose of the Glow-

plug circuit on diesel vehicles is to pre-heat the Combustion Chamber

before the vehicle is started.

When a Remote Starter is installed on a diesel vehicle, the Glow- plug

section of the Ignition circuit must be activated and allowed to operate

before the vehicle is remote-started. For that purpose, the Glow-plug

input wire of the module must be connected to the Glow-plug indicator

light of the vehicle. The module will only accept positive Glow-plug input

signals, if the signal is negative, use a relay to invert its polarity. A diode

must be added between the negative Glow-plug trigger on the relay and

the negative Glow-plug wire of the car. This is to prevent feedback

effects on the Glow-plug indicator light on the instrument cluster: the

light on the dash would come on because of the feedback, even though

the circuit is off.

When the user remote-starts the vehicle:

The module will power up the Ignition circuit and wait to engage the

Starter Motor while the Glow-plug indicator light is still on.

The module will engage the Starter Motor as soon as the Glow-plug

light (+) goes out.

Minimum waiting time is 4 seconds.

Maximum waiting time is 30 seconds (approximately).

If no Glow-plug wire is found on the vehicle, the Glow-plug input on the

module may be “timed out”. The module will power up the Ignition and

Glow-plug circuits and simply wait for the time-out before starting.

Keeping the Glow-plug input wire of the module unconnected will hold

the ignition on for the preprogrammed delay.

Warning! Please program the tach before connecting the glow-plug

input to the vehicle.
