(cont.)
(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.
