ENGINE SHUTDOWN
Following retransfer back to the "Utility" source, an
"engine cool-down timer" on the circuit board starts
timing. When that timer has timed out (approximately
one minute), circuit board action will de-energize the
circuit board's run relay (K2). The following events will
then occur:
• The DC circuit to Wire 14 and the fuel solenoid (FS)
will be opened. The fuel solenoid (FS) will de-
energize and close to terminate the engine fuel
supply.
• The hourmeter (if equipped) connected to Wire 14
will be opened and clock function of the hourmeter
will stop.
