ELECTRICAL
The electric clutch controls the engagement and
disengagement of the Power Take Off (PTO) pulley.
1. Remove the control panel from the tank by removing
4 screws.
2. With a VOM, place the negative probe to the battery
negative cable. Turn the ignition key to the RUN
position.
3. Place the positive probe of the meter to the I (orange
wire) terminal. You should read the DC battery
voltage level on the meter.
4. Move the positive probe of the meter to the G (black
wire) terminal. You should get 0 volts DC on the

ELECTRIC PTO CLUTCH
Purpose
Location
The electric clutch is located on the PTO end of the
crankshaft (Fig. 352).
Fig 352 DSC-2552
The PTO clutch is composed of three major components;
the eld, the clutch plate, and the friction plate. The
clutch plate always turns with the engine. The eld is a
coil of wire wound around an iron core, which acts like an
electromagnet when power is applied.
The friction plate is the only piece that can slide inward
and outward on the crankshaft axis. It is spring loaded
away from contact with the clutch plate. When the clutch
is not energized, the clutch plate rests against the brake
material opposite the clutch plate. When energized the
friction plate is drawn into the clutch plate magnetically
and the two rotate as one component.
