Supervisor Speed Limit Switch
The supervisor speed limit switch is open in OFF posi-
tion (key vertical) and closed in ON position (key rotated
clockwise). The speed limit switch is one of several in-
puts for the vehicle controller and allows the speed of the
vehicle to be limited.
Test the switch by disconnecting the wiring and connect-
ing a continuity tester across switch terminals A and D
(Fig. 26). Rotate key to ON position: there should be an
indication of continuity. Rotate key to OFF position:
there should be no continuity.

IMPORTANT: Make sure to observe polarity on the
alarm terminals when testing. Damage to the alarm
may result from an improper connection.

ponent. Do not test the alarm using jumper wires
from the vehicle battery pack (48 VDC).

from switch. Raise cargo box and remove controller cov-
er.
2. Disconnect wire harness connectors from alarm

source to the alarm terminals noting polarity shown on
alarm decal.
