Test Procedure 9F – Pin 9
See General Warning, Section 10, Page 10-1.
Pin 9 in the 16-pin connector provides a connection point for the Tow/Run switch to the speed controller. The
switch provides a +48 volt signal to the speed controller through pin 9 when the Tow/Run switch is in the RUN
position.
NOTE: There is a diode in the wire connected at Pin 9.
1. Disconnect the batteries and discharge the controller. See Disconnecting The Batteries on page 10-3.
2. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position
jack stands under the frame crossmember between the spring mount and side stringer, just forward of
each rear wheel.
See WARNING “Lift only one end...” in General Warning, Section 10, Page 10-2.
3. Disconnect the 16-pin connector at the speed controller.
4. With the multimeter set to the diode test function (
ç
), connect the black (–) probe of the multimeter to
the light green wire terminal of the two-pin connector at the Tow/Run switch and the red (+) probe of the
multimeter to the pin 9 terminal
(Figure 11-19, Page 11-32) . See following CAUTION . The reading
should indicate an overload (no continuity). A diode is designed to conduct current in one direction only.
If a diode conducts current (shows continuity) with the meter probes as described, the diode has failed
and must be removed from the wire harness.
See Pin 9 Diode Removal, Section 13, Page 13-16.
CAUT ION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.
5. Reverse the multimeter probes and note the reading. With the black (–) probe of the multimeter on the
pin 9 terminal of the multi-pin connector and the red (+) probe of the multimeter on the light green wire
at the Tow/Run switch, the meter should read approximately 500 mV; however, a range of 400-600 mV
is acceptable
(Figure 11-20, Page 11-32) .
6. If any other reading is obtained, check the following items:
