(+) Glow-Plug
input
In Diesel Mode, this positive input will monitor the Glow Plug Light:
it will wait for up to 18 seconds until the Glow-plug Light goes out
before allowing the Remote Car Starter to proceed to cranking the
Engine. Connect to the side of the Glow-plug Light which is positive
when the Light is on.
Note: the Remote Car Starter will nevertheless proceed to
cranking the Engine if the Glow-plug Light is still on after the 18-
sec. delay (25 sec. when the Run Time is set to 30 min.).
A Note on the Diesel Glow-plug Indicator Light:
(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 Remote Car Starter must be connected
to the Glow-plug indicator light of the vehicle.
Caution! The Remote Car Starter will only accept positive Glow-
plug input signals, therefore negative Glow Plugs should only be
connected using relays to invert the 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 Remote Car Starter will power up the Ignition circuit and
wait to engage the Starter Motor while the Glow-plug
indicator light is still on.
The Remote Car Starter will engage the Starter Motor as
soon as the Glow-plug light (+) goes out.
o Minimum waiting time is 3 seconds.
o Maximum waiting time is 18 seconds.
If no Glow-plug wire is found on the vehicle, the Glow-plug input on
the Remote Car Starter may be “timed out”. The Remote Car
Starter will power up the Ignition and Glow-plug circuits and simply
wait for the time-out before starting:
Connecting the Glow-plug input wire of the Remote Car
Starter to Ignition will hold the ignition ON for the maximum
waiting time (18 sec., recommended).
Keeping the Glow-plug input wire of the Remote Car Starter
unconnected will hold the ignition ON for the minimum
waiting time (3 sec., not recommended in very cold
environments).
Connect the Glow-plug wire to the Ignition wire only after the Tach
programming has been completed: connecting the Glow-plug wire
is one of the very last steps in the installation process.
