low fuel.
Invalid range control switch
position.
Add more fuel. If there is less
than half a tank of fuel,check for
proper operation of the fuel float.
If the float is at the top of the
tank, the resistance across its
terminals should be less than
100 ohms. If the float is on the
bottom of the tank, the resistance
across its terminals should be
greater than 175 ohms. If the
float is OK, check the leads and
connections between the float,
the fuel gauge and the engine
protection board. See the Wiring
Diagram. If the above checks do
not reveal the problem, the
engine protection board may be
faulty.
Check for proper selector
switch/handle alignment.
Check the selector switch and
associated wiring. See the Wiring
Diagram. If the problem persists,
the control board may be faulty.
