SECTION 10J. FUSES & CIRCUIT BREAKERS
FUSE (F1) TEST
The fuse is located in the fuse block mounted on the
right side of the mower frame in front of the engine
compartment. A plastic cover protects the fuses and
must be removed for access.
Test the fuse as follows:
1. Visually inspect and replace a blown fuse.
2. If the fuse does not appear to be blown, check the
fuse as follows:
a. Set the multimeter to the continuity scale.
b. Connect one test lead to each fuse blade, see
Figure 10J-1.
• Continuity should be available between the
fuse blades. If not, replace the fuse.
Figure 10J-1. Fuse Test
CIRCUIT BREAKER (CB1) TEST
A 40 Amp circuit breaker (CB1) protects the electrical
system between the alternator and battery voltage cir-
cuit. The circuit breaker is mounted near the relays
under the hood. When tripped, the circuit breaker
opens, interrupting the flow of current from the alterna-
tor to the battery circuit. The circuit breaker can be
tested using the following procedure.
1. Shut off the engine and remove the ignition key.
Allow the engine to cool completely.
2. Set the multimeter to 20 volts DC.
3. Connect black test lead to the battery negative (-
NEG) terminal.
4. Connect the red test lead to each of the circuit
breaker terminals in turn.
• The multimeter should indicate battery voltage
at both circuit breaker terminals. If not, replace
the circuit breaker.
