Backup Switch (Optional Kit)
The optional backup switch is a four (4) terminal, two (2)
circuit switch that is used to energize the backup alarm
when the shift lever is in the reverse position. The nor-
mally open switch circuit is used while the normally
closed switch circuit is not used. If equipped, this switch
is attached to the shift bracket in the seat base (Fig. 30).
Switch Testing
1. Position vehicle on a level surface, set parking
brake, turn ignition switch OFF and remove key from
switch. Make sure that vehicle shift lever is in the NEU-
TRAL position.
2. Remove four (4) screws and carefully slide shift
bracket assembly from front of seat base to gain access
to backup switch.
3. Unplug vehicle wire harness connector from backup
switch.
4. With the use of a multimeter (ohms setting), check
that the normally open switch contacts (Fig. 31) do not
have continuity when the switch plunger is extended.
The contacts should have continuity when the switch
plunger is fully depressed.
5. When testing is complete, connect wire harness con-
nector to backup switch. Slide shift bracket into seat
base and secure with four (4) screws.
