Starting System: Description and Operation
OPERATIONVoltage is present at the ignition switch and starter contacts at all times.
With the ignition switch in "START" (and the clutch pedal position switch, park/neutral position switch or manual lever position sensor closed), current flows through the ignition switch, the appropriate transmission switch (mentioned above) and the starter relay coil to ground. The starter relay coil is energized and its contacts close.
Current now flows from the battery directly through the starter relay contacts and starter motor to ground; the motor runs to crank the engine.
With the Ignition Switch in "START/RUN", voltage is applied to the Wait To Start Indicator, which is grounded by the Glow Plug Controller. See Glow Plug Control for Glow Plug Control's circuit operation. Description and Operation
