BACKLAP SWITCH TEST
The backlap switch is mounted to the rear of the fuse/
relay boxes. The switch has two positions (ON/OFF)
used in conjunction with the reel switch to control the
reverse rotation of the hydraulic reel motors. The
switch can be tested as follows:
1. Shut down the engine and remove the ignition
key.
2. Locate the backlap switch and remove the wiring
harness connector, see Figure 10G-6.
3. Set the multimeter to the continuity scale.
4. Place the switch in the OFF position
(Figure 10G-6). Check continuity between all ter-
minals.
Continuity should be available between terminal 2
and terminal 1 and between terminal 5 and termi-
nal 4 only.
5. Place switch in the ON position. Check continuity
between all terminals (Figure 10G-6).
Continuity should be available between terminal 2
and terminal 3 and between terminal 5 and termi-
nal 6 only.
NOTE:
Replace the switch if it does not meet the above
test results.
