Taylor-Dunn SS5-34 Operation, Troubleshooting Manual page 97

Connect a voltmeter across the Reverse Solenoid
coil terminals. Refer to your vehicles wiring
diagram to identify the position of the reverse
solenoid.
Close all interlock switches, turn the Key
Switch ON, and place the F&R Switch in
reverse.
Depress the accelerator pedal fully.
•
If the voltage is not at battery volts then
go to the F/R Switch sequence.
Set the test light voltage to the same voltage as
the battery volts.
Connect the test light across the normally open
contacts of the reverse solenoid. Refer to your
vehicles wiring diagram to identify the position
of the reverse solenoid.
Close all interlock switches, turn the Key
Switch ON, and place the F&R Switch in
reverse.
Depress the accelerator pedal fully.
•
If the light comes on then the Reverse
solenoid has failed. Stop trouble shooting
here and repair the problem. When the
repair is completed, completely retest the
vehicle before lowering the drive wheels
to the ground.
Connect the test light across the Normally Closed
contacts of the Forward solenoid. Refer to your
vehicles wiring diagram to identify the position
of the forward solenoid.
Close all interlock switches, turn the Key
Switch ON, and place the F&R Switch in
Reverse.
Depress the accelerator pedal fully.
•
If the light comes on then the Forward
solenoid has failed. Stop trouble shooting
here and repair the problem. When the
repair is completed, completely retest the
vehicle before lowering the drive wheels to the ground.
Stop, do not continue. If you reached this point without a solution, then you may have an
unanticipated problem or have made an error during testing. It is important to review the
trouble shooting steps that have led to this point. The tests may need to be repeated.
