HEATED FRONT SCREEN

CIRCUIT OPERATION

CIRCUIT OPERATION

This operates only with the engine running, which is
determined by the HEVAC panel. In the off state, the
signal is at 12 volts. When the Heated Front
Windscreen is activated, the signal is switched to 0
volts. This provides the ground required for relay 5 to
be pulled in, as there is an ignition feed on the other
side of the coil provided by relay 15. This relay
energises one half of the heated screen elements.

Once relay 5 has been energised, a 12 volt signal is
provided to the coil of relay 4. The other side of the
coil is connected directly to ground, thereby
energising the relay and switching on the other half
of the elements.

There is also a feed spliced from the harness which
provides the petrol Engine Control Module with a
signal that tells the unit there will be a large electrical
load turned on/off.
