TEST 33 - TEST WIRE 167

PROCEDURE:
1. Set a voltmeter to measure DC voltage.

2. Remove the J2 connector from the circuit board. Connect the

positive meter test lead to Pin Location J2-5, Wire 167 on the
removed harness connector. See Figure 6-44 Connect the
negative meter test lead to frame ground. Place the Start-Run-
Stop switch (SW1) to start. The engine will crank and 12 VDC
should be measured. If 12 VDC is measured, stop testing. If 12
VDC is not measured continue testing.

(TB1). Connect the negative meter test lead to frame ground.
Place the Start-Run-Stop Switch (SW1) to start. 12 VDC
should be measured. If 12 VDC is measured, replace Wire 167

5. Connect the positive meter test to Wire 15 at SW1. See Figure

6-46. Connect the negative meter test lead to frame ground.
12 VDC should be measured. If 12 VDC is measured, replace
SW1. If 12 VDC is not measured repair or replace wire 15
between SW1 and the Starter Contactor Relay (SCR).
