IGNITION SWITCH & JUMPER HARNESS TEST
PROCEDURES
STEP DETAILS
Make vehicle safe. Ignition switch off and key removed.
Parking brake set.
Disconnect jumper harness from main
harness.
Connect ohmmeter leads to pins 3 and 4 of
jumper harness (See Figure 5-1).
Readings should be as shown below when
ignition switch is in position shown:
Reverse………………1 k ohms
Off……………………..open circuit
Hi………………………. 2 k ohms
Lo……………………… 4 k ohms
Connect ohmmeter leads to pins 2 and 3
(readings same as pins 3 and 4). See Figure
5-1. Readings should be as shown below when hi-lo-
reverse switch is in position shown:
Reverse………………1 k ohms
Off……………………..open circuit
Hi………………………. 2 k ohms
Lo……………………… 4 k ohms
Connect ohmmeter leads to pins 2 and 4.
See Figure 5-1 Should show near zero ohms in all switch
positions except “off”. Off position should show
open circuit.
Further action. If any readings are not as shown (or very close),
disconnect jumper harness from switch and
check jumper harness and switch individually.
If readings were ok, go to next steps.
Connect ohmmeter leads to pins 32 and 33
on large controller connector. See Figure 5-
2.
Reconnect jumper harness to main harness.
Readings should be as shown below when hi-lo-
reverse switch is in position shown:
Reverse………………1 k ohms
Off……………………..open circuit
Hi………………………. 2 k ohms
Lo……………………… 4 k ohms
Connect ohmmeter leads to pins 32 and 31
on large controller connector. See Figure 5-
2. Readings should be as shown below when
ignition switch is in position shown:
Reverse………………1 k ohms
Off……………………..open circuit
Hi………………………. 2 k ohms
Lo……………………… 4 k ohms
Connect ohmmeter leads to pins 31 and 33
on large controller connector. See Figure 5-
2. Should show short circuit in all switch positions
except “off”. Off position should show open
circuit.
Replace wiring harness. If any reading taken through main harness shows
different than described.
