Engine Shutdown Solenoid Test. (Used on Model 350 PAWN only)
INITIAL SETUP
Tools
General Safety instructions
General Mechanic’s Tool Kit (Appendix B, Section III,
Item 1)
To prevent rolling or sliding, do not work on equipment
that is not securely stabilized.
Equipment Conditions
Equipment shut down, paragraph 2.5.2.
Do not work on equipment without following standard
shop safety precautions.
a.
Check for a good ground connection between black wire (figure 4-18.1,1) of solenoid (2) and engine. If in doubt,
also check continuity between engine ground and battery return to insure a good ground.
b.
Remove sleeving from red and white wires (3 and 4), and disconnect spade connectors.
c.
Apply 12 V dc to red wire (3) of solenoid (2).
C A U T I O N
Red wire is connected to a hold-in coil while white wire is connected to a pull-in coil.
Because pull in coil draws a large amount of current, coil may be damaged if power is
applied for too long.
d.
Briefly apply 12 Vdc to the white wire (4) and note that plunger (5) retracts, pulls up fuel lever (6) on the engine
to open the fuel valve, and stays retracted when power is disconnected from white wire as long as power remains
applied to the red wire.
