TROUBLE SHOOTING CHART FOR ELECTRIC START MODEL
TROUBLE LOOK FOR REMEDY
Engine fails to start. Safety System A. Check for a blown fuse in the wire leading from the
positive terminal of the battery.
B. Before checking the safety system further, be sure the
clutch control and the blade control are disengaged; only
the starting system is being checked. Therefore remove
the spark piug lead and ground it to prevent the engine
from starting.
C. Attach a wire (minimum 18 gauge) to the positive ter­
minal of the battery and touch the other end to the
small terminal (coil primary) of the solenoid. If the en­
gine cranks, the problem is in the safety system.
D. Check for continuity from the battery to the solenoid.
NOTE: The positive terminal of the battery should have
a large cable (#8 guage) and a small wire (#18 gauge)
attached to it.
E. Check all wires and cable for tightness.
F. Use a #8 gauge wire and jump between the two large
terminals of the solenoid. If the unit starts, replace the
solenoid.
G. If the unit fails to start after following the above pro­
cedure the problem is probably in the starting motor of
the engine.
