Measuring Clutch Current Draw

1. Disengage the PTO, set the parking brake, turn the
ignition OFF, and remove the key.
2. Disconnect the clutch wire connector from the wire
harness.
3. Set the multimeter to check amps (10 amp scale).
4. Connect the positive meter lead to the tractor
terminal (1) of the clutch wire (Fig. 729).
5. Connect the negative meter lead to the correspond-
ing wire terminal (3) (Fig. 729).

Solenoid

Purpose

The purpose of the solenoid is to connect the battery to
the starter motor on the engine when the ignition switch
is turned to "START". The solenoid is used to protect the
ignition switch from the high current drawn from by the
starter motor (Fig. 730).
