Component Tests
J. Accessory Power Connector Test
See Figure 46.
1. Disconnect any accessory connector from the acces-
sory power plug.
2. Set VOM to DC Volts.
3. Connect the negative (-) test meter probe to the top
pin (male) of the accessory power connector.
4. Connect the positive (+) test meter probe to the sec-
ond pin (female) of the accessory power connector.
5. Press the height of cut switch to the up position. The
connector should have 12 volts dc.
6. Connect the positive (+) test meter probe to the top
pin (male) of the accessory power connector.
7. Connect the negative (-) test meter probe to the sec-
ond pin (female) of the accessory power connector.
8. Press the height of cut switch to the down position.
The connector should have 12 volts dc.
If either position of the switch did not function properly,
begin further troubleshooting by checking the connectors
between the accessory power connector and the switch
and check the wiring. Then check the height of cut switch.

K. Cruise Control Switch Test
The cruise control switch has a N.C. contact and closes
when the cruse control is engaged. When the cruise con-
trol lever is in the disengaged position, the lever pushes
in the plunger on the switch, opening the contacts.
SWITCH TESTS
NOTE: It may be easier to test the switch if the switch is
removed. See Component Location and Replacement for
switch removal procedures, earlier in this section.
1. Pull the wire harness off the back of the switch.
2. Set VOM to Ohm. With the cruise control lever in the
engaged position (plunger not depressed) probe the
switch terminals (see Figure 45). The VOM should
show continuity (zero ohm).
3. Release the cruise control lever (disengage cruise
control). Probe the switch terminals (see Figure 45).
The VOM should show no continuity (open).
4. Replace a switch that does not pass all tests.
