ELECTRICAL SYSTEM

10G-13

SECTION 10G. SWITCHES

GENERAL

This section provides instructions for testing the vari-
ous switches in the electrical system. Repair is limited
to replacement of components found faulty during test-
ing. See Section 10M for location of components.

Switches can be defined as NO (normally open) or NC
(normally closed). A normally open switch blocks the
flow of current until the switch is activated. A normally
closed switch allows current to flow until the switch is
activated. Testing a switch allows the mechanic to
determine if the switch actually opens or closes when
activated and if it is activated.

SEAT SWITCH

The seat switch allows the engine to run when the
operator is in the seat and the deck is operating. If the
operator leaves or falls from the seat with the engine
running, the engine shuts down. 

See Figure 10G-1 and test switch as follows:

1. Unplug the switch from the harness.

2. Set the multimeter to the continuity scale.

3. Connect one lead to each side of the seat harness 

connector. 

The seat switch should be open with no continuity 
displayed on the multimeter.

4. Depress the seat switch or have a helper sit in the 

seat.

The seat switch should be closed and a reading of 
0 to 0.5 

Ω

 (Ohms) should display on the multime-

ter.

NOTE:

Replace the switch if the test results are not satis-
factory.

Figure 10G-1. Seat Test

IGNITION SWITCH

1. Disconnect the ground (black) cable at the battery.

2. Remove the steering tower cover.

3. Remove the wiring harness connector from the 

ignition switch.

4. Set the multimeter to continuity scale.

5. See Figure 10G-2 and Figure 10G-3 all switch 

positions as follows:
a. With the ignition switch in the OFF position, 

check all pin positions for continuity.

Continuity should not be available between 
any of the pin positions.

NOTE:

If a reading of 0.5 

Ω

 (Ohms) or more exists in any

of the following tests, the ignition switch is faulty
and must be replaced.

b. Place the ignition switch in the RUN position 

and connect one test lead to terminal AC and 
one lead to terminal 30. Check all pin posi-
tions.

Continuity should be available between termi-
nals 30 and AC.

c. Hold the ignition switch in the GLOW PLUG 

position and connect one test lead to terminal 
30 and one lead to terminal 19. Test all pin
