4. Connect the meter lead wires to the wires in
the clutch connector.
The meter should read between 2.40 and
3.40 ohms. If the readings are not within
specifications, the coil has failed and the
clutch must be replaced.
If the resistance is within specifications, the
electric clutch is not the source of the
problem.
SAFETY INTERLOCK SYSTEM
Purpose
The safety interlock system is designed to
prevent the engine from starting unless:
1. You are sitting on the seat.
2. The brake pedal is depressed.
3. The power take off (PTO) is OFF.
The system will also kill the engine if you
attempt to operate the clutch or drive system
when you are not in the seat.
Testing
1. Set the parking brake. Move the PTO to ON.
Now turn the ignition key to START; the
engine should not crank.
2. Push the PTO to OFF and release the
parking brake. Now turn the ignition to
START; the engine should not crank.
3. Set the parking brake and move the PTO to
OFF. Start the engine. While the engine is
running, release the parking brake and rise
from the seat; the engine should stop.
