Component Tests
P. Circuit Breaker Test
See Figure 51.
The circuit breaker is connected to one of the small sole-
noid posts along with the positive battery cable.
1. Set the VOM to VDC.
2. With the negative probe, touch ground.
3. Touch the positive probe to one post of the circuit
breaker, and then the other. Both posts should have
close to full battery voltage going to them. If not,
replace the breaker.
4. Set VOM to Ohm.
5. Disconnect the circuit breaker leads and probe both
circuit breaker terminals. If the VOM reads 5 ohm or
more, replace the circuit breaker.
Q. PTO Clutch
Refer to Section 16, PTO CLUTCH SERVICE, for com-
pete PTO clutch testing information and replacement
procedures.
R. Headlight Switch Test
1. If needed, remove the steering wheel and dashboard.
(See Section 8, POWER STEERING SYSTEM SER-
VICE.)
2. Set the VOM to Ohm.
3. With the switch in the OFF position, probe both termi-
nals (Figure 52). The VOM should read no continuity.
4. Turn the switch to ON. The VOM should read conti-
nuity.
S. Fuel Solenoid Test
Refer to the engine manufacturer's operators manual for
information relating to engine components.
1.Turn the ignition switch from OFF to RUN. There
should be an audible "click" as the shut-off solenoid
opens.
If there is no "click" use a VOM set to VDC. Test the
voltage between the solenoid lead and ground. With
the ignition switch in the RUN position, the lead
should have 12 volts. If not, check the ignition switch
and wiring.
If the solenoid is receiving 12 VDC and is not open-
ing, replace the solenoid.

T. Voltage Regulator
The voltage regulator is part of the engine, refer to the
engine manufacturer's operators manual for information
relating to engine components. On some alternators the
voltage regulator is built in.
U. Alternator
Refer to the engine manufacturer's operators manual for
information relating to engine components.
