Also check the 16-pin connector at the speed controller.
See Test Procedure 15 – 16-Pin
4.
Test REVERSE INPUT.
4.1. Access the Monitor menu and select REVERSE INPUT by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or FORWARD position.
4.2. Place the Forward/Reverse switch in the REVERSE position. The IQDM should indicate that REVERSE
INPUT is ON. If the IQDM indicates any other reading, check vehicle wiring.
Also check the 16-pin connector at the speed controller.
See Test Procedure 15 – 16-Pin
5.
If the IQDM displays readings other than those described above and the wiring is found to be correct, proceed to
the following procedure,
Forward/Reverse Rocker Switch Test without the IQDM Handset
.
Forward/Reverse Rocker Switch Test without the IQDM Handset
1.
If necessary, see Testing Basics on page 28-16.
2.
Place the Tow/Run switch in the RUN position and the Forward/Reverse switch in the NEUTRAL position.
3.
Remove Forward/Reverse switch from its housing by carefully prying up each side with a small, flat-tip screwdriver.
4.
Back-probe the following three wires connected to the Forward/Reverse switch in each position:
4.1.
Orange Wire
– The orange wire provides power to the switch and should show BPV coming to the switch in all three
positions.
If the orange wire does not show BPV, check the 15-amp fuse, Tow/Run switch, red-to-pink wire spade
terminal connection and related wiring.
4.2.
Brown Wire
– The brown wire should show BPV in FORWARD.
– The brown wire should show zero (0) volts in NEUTRAL and REVERSE
If the brown wire shows voltage in NEUTRAL, the switch may have corrosion across the contacts or the
switch has failed CLOSED and must be replaced.
See Forward/Reverse Rocker Switch Removal on
If the brown wire does not show BPV in FORWARD, the switch may have corrosion on the contact or the
switch has failed OPEN and must be replaced.
See Forward/Reverse Rocker Switch Removal on
4.3.
Blue Wire
– The blue wire should show BPV in REVERSE.
– The blue wire should show zero (0) volts in NEUTRAL and FORWARD.
If the blue wire shows voltage in NEUTRAL, the switch may have corrosion across the contacts or the switch
has failed CLOSED and must be replaced.
See Forward/Reverse Rocker Switch Removal on page 29-3.
If the blue wire does not show BPV in REVERSE, the switch may have corrosion on the contact or the switch
has failed OPEN and must be replaced.
See Forward/Reverse Rocker Switch Removal on page 29-3.
.
5.
When installing the Forward/Reverse switch into its housing, orient the three wire terminals towards the front of
the vehicle (i.e. biased closer to the front of the switch housing and farther from the rear body).
