Starter Solenoid Circuit & Operation
The starter solenoid B+ (battery positive) input is
controlled by the ignition switch when in the START
position. The starter solenoid B- (battery negative) is
controlled by the Kill Relay.
The Kill Relay will only ground and activate the starter
solenoid and allow the engine to start when:
- The key is in the start position.
- Proper battery voltage is present at the key
switch, kill relay, and starter solenoid
- Proper ground is present at the battery, chassis,
and kill relay.
- The PTO switch is OFF, supplying battery voltage
to the Park Brake Switch.
- Both handles are in the neutral position and both
neutral switches are CLOSED, supplying battery
voltage to the control side of the kill relay.
Note: The engine will not crank over to start when
the PTO switch is ON.
