6.4 Electric requirements
to be able to start the
machine
A number of electrical conditions must be
met for the engine to start. If one or sev-
eral of the conditions are not met the en-

In order to start the engine the following
conditions must be met on the connector
to the control unit (for position see page

1. Ground at switch position “G”
Receives ground connection via the
PTO relay and the seat switch when
the PTO is not activated and someone
sits on the seat.
2. Voltage in position “C”
Receives current through the fuse and
the pedal switch when the pedal for
the parking brake is depressed when
the ignition is on.
3. No pulses at position “H”
The engine must not be running.
4. Voltage in position "E"
Is obtained when the starter key is in
the “START” position.
When points 1-4 are met the relay in the
control unit closes and the starter motor
operates.

Check the points above to see if one or
more of the conditions is not met and is
causing the machine not to start.
