b. Disassembly
DO NOT disassemble the ignition switch. Replace a
defective switch with a new part.
c. Inspection and Replacement
To determine the proper operation of the ignition switch,
and using the following chart, test the terminals on the
back of the switch for continuity with an ohmmeter.
Test the Ignition switch for continuity, by checking from
the terminal “BAT” (19) to each of the other terminals in
each switch position. Continuity (X) should be present as
indicated in the following table:
If all terminals do not show proper continuity, replace the
ignition switch.
d. Ignition Switch Installation
1. Use the nuts removed in step 6 and connect the wire
ends of the cab harness to the ignition switch as
follows:
• Wire [PB2] (TAN) to “IGN” (20) terminal
• Wire [PB6] (RED/WHT) to “ST” (21) terminal
• Wire [PB1] (RED/TAN) to “BAT” (19) terminal
2. Reach up and under the dash to work the ignition
switch (12) into the mounting hole (17) on the lower
right side of the dash.
3. Align the ignition switch (22) so that when it is in the
OFF (23) position, the key slot (18) is positioned
vertically (straight up and down). Install the knurled
nut (11) securing the ignition switch to the dash. DO
NOT overtighten.
4. If the vehicle has dual batteries, connect both
negative battery cables (3 and 4) to both batteries.
Connect the lower negative battery cable (3) to the
negative (-) terminal on the lower battery (5). Swing
the upper battery box (8) in and make sure that the
lip (7) on the upper battery box slides below the
knob (6). Secure in place with the knob.
5. Lower and lock engine cover. To release and lower
the engine cover (1) from the fully raised position, lift
up slightly on the cover and push the upper part of
the right gas shock (2) (orange tab) to the left. Line
up the upper part of the shock lock tube with the
lower part of the gas shock and pull the cover down
to the closed position.
