Fig 403 diag 3-7
5. Connect the negative meter lead to the clutch
harness terminal (3), Fig. 403.
6. Connect a short jumper lead from terminal (2) to
terminal (4) Fig. 403.
7. Turn the ignition switch to the “RUN” position. Turn
the PTO switch to the “ON” position.
8. If the meter reading is 6.5 amps or above, the
system is functioning properly. If the meter reading
is below 6.5 amps, check the electrical system for
problems (i.e., the battery, ignition switch. PTO
switch, or wiring harness). Make sure the negative
side of the wiring has a good connection to chassis
ground.
Solenoid
Purpose
The solenoid’s purpose is simply to connect the battery
to the starter motor when the ignition switch is turned
to “START”. The solenoid is used to protect the ignition
switch from the high current drawn by the starter motor.
The starter solenoid is located under the left hand fuel
tank (Fig. 404).
