Pin Problems?
I
f your tank suddenly loses throttle control and the FUEL CONTROL FAULTY
caution light comes on during operation, don’t panic.
The problem could be something as simple as an electromechanical fuel system
(EMFS) connector pin, NSN 5315-01-205-8647, that’s vibrated loose and fallen out.
Before calling for a tow, try shining a
flashlight into the engine compartment.
Most of the time the pin ends up in the small
cupped area under the EMFS. If you find
the pin, slip it back into place and you’re
good to go.
Just make sure your mechanic replaces
the pin when you get back to the motor
pool. The next time it falls out, you might
not find it.

tarting up and shutting down your tank should be as easy as flipping a switch, right
drivers?
Wrong!
If you want your tank to start tomorrow, follow these critical startup and shutdown
tips today:
Look for missing pin here
4.
Always idle the engine at least
two minutes
to cool
it off before shutdown. And never gun the engine dur-
ing or after the cool-down period. Idling prevents heat
soak, which cracks turbine rotors, clogs oil passages,
and ruins the rear module.
Also, ignoring the cool-down period results in
enough heat to boil the engine oil. That cokes bearings
and clogs oil ports. Dry bearings will ruin the engine.
Refer to your
-10 TM for the
complete picture on
startup and shut-
down procedures.

3.
Never turn OFF any circuit breaker
once the start cycle has begun.
Violating steps 2 or 3 puts too much
fuel into the engine. The extra fuel
explodes, damaging the engine.
2.
Never press the START button for
more than one second at a time.
