CIRCUIT OPERATION
Starting System
When the Ignition Switch (X274) is switched to
position III, the BeCM (Z238) grounds the starter
solenoid relay inside the Engine Compartment Fuse
Box (P125) which then energizes, applying battery
voltage to the Starter Solenoid (K136) and Starter
(M134).
Charging System
When the Ignition Switch (X274) is in position II, the
BeCM (Z238) turns the charge warning light on via
the datalink connection to the Instrument Pack
(Z142)
When the Generator (Z106) starts to produce power,
the BeCM (Z238) gets an input signal on Pin 15 and
turns off the charge warning light.
For the Diesel engine this signal is also used as an
input signal for the fuel pump relay inside the Engine
Compartment Fusebox (P125) to make sure that the
Fuel Pump (M109) is only supplied with power when
the engine is running.
If the Generator (Z106) fails to produce power, the
charge warning light remains illuminated.
