Key Switch
1. Make sure the key-switch is in the “OFF” position, then remove the key.
2. Place the forward-reverse switch in the center “OFF” position.
3. Set the park brake.
4. Place blocks under the front wheels to prevent vehicle movement.
The rear drive wheels may rotate during some of the following tests. Block the
front wheels, raise the rear drive wheels off the ground, and support the vehicle
with jack stands. Failure to do so may cause the vehicle to move and cause
severe bodily injury and/or property damage.
Rotating rear drive wheels are a potential hazard. Keep hands, arms, legs and
loose clothing away from the rear drive wheels while conducting tests. Failure
to do so may cause serious bodily injury.
Test all interlock switches and/or interlock relays (if equipped) for continuity. Depending on the model of
your vehicle, it may have a seat interlock, Foot interlock, Charger interlock, special order interlock or any
combination of the above. Refer to the wire diagram at the end of this section for location of the interlocks.
NOTE: Due to the many different configurations possible for special order interlocks,
they will not be included in this text. Refer to the option list for your truck or
contact your Taylor-Dunn
®
Representative for more information.
If you do not know how to test for continuity, refer test to a qualified technician.
