This magnet (A) is mounted below a control
plate (B). The control plate is connected to the
speed control lever. When the cruise control is
activated, the magnet clamps the control plate
in position which holds the speed control lever
at the desired speed.
Tapping the brake pedal or shutting the switch
off deactivates the system. The foot pedal can
be used to override the cruise control; the
pre-set speed will resume when the pedal is
released.
NOTE: Activating cruise in neutral or at very
slow speeds will prevent full speed operation.
Disconnect the three pin connector from the
cruise control module. Turn the ignition switch
to the "on" position. Make sure the parking
brake is disengaged. Measure the voltage at
each of the pins in the following conditions:
Cruise Cruise
Wire Color
Off On
Yellow 0 V 12 V
Brown 0 V 0 V
Black 0 V 0 V
If you do not get these results, the problem is in
the switches or wiring between the module and
the switches or magnet.
Reconnect the three pin connector to the
module. Measure the voltage at each of the
pins on the connector in the following
conditions:
