panel indicators, and starter solenoid
wire
The ECM monitors the wiring to, and condition of, the fuel solenoid and the
wiring to, and condition of, the starter solenoid.
If the wire (1) to the fuel solenoid is disconnected or the fuel solenoid is
faulty, the following results occur.
• The control panel indicators (2) will flash immediately after the transmit-
ter is turned on.
• The red LEDs of the light ring will illuminate solid red.
• The engine will not crank.
Reconnect the wire or replace the fuel solenoid to enable the machine to
start.
If the wire (3) to the starter solenoid is disconnected or the starter solenoid is
faulty, the following results occur.
• The control panel indicators will flash immediately after the starter push-
button is pressed.
• The red LEDs of the light ring will illuminate solid red.
• The engine will not crank.
Reconnect the wire or replace the starter solenoid to enable the machine to
start.
