ings − Foldout Drawings in this manual for additional in-
formation.
When the ignition switch input is in the RUN position
(KEY RUN ON), the following output should occur
(Fig. 35):
OK RUN ON − TEC output 2: For gasoline engine
machines the engine ECU ”ignition” is should ener-
gize, and for diesel engine machines the fuel stop/
run solenoid hold coil should energize.
NOTE: The engine will not start if the operator is not in
the seat and the parking brake is disengaged, the spray
pump is engaged and the traction pedal is in forward or
reverse.
When the ignition switch input is turned to the START
position (KEY RUN ON), the following qualifiers are re-
quired for the engine starter to energize (Fig. 36):
SEAT ON and/or PARKING BRAKE ON: Operator
seat needs to be occupied or the parking brake
needs to be applied.
PUMP OFF: The PUMP switch must be disengaged.
NEUTRAL ON: The traction pedal must be in neutral.
If the proper inputs and qualifiers exist, the following out-
puts should occur (Fig. 36):
START ON − TEC output 1: For gasoline engine ma-
chines the engine ECU “start” should energize, and
for diesel engine machines the start relay and glow
controller “start” should energize and the starter mo-
tor should engage.
NOTE: The OK RUN output should remain ON when
the ignition switch is in the START position.
