Starting System: Description and Operation


Voltage is present at the Ignition Switch and Starter Relay contacts at all times.

With the Ignition Switch in START (and the Clutch Interlock Switch, Backup/Neutral Safety 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.

The TFI Ignition Module also receives a start signal with the Ignition Switch in START (and the appropriate transmission switch closed).
