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.

3.Connect the positive test lead to Wire 167 at Terminal Block 1 (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 between TB1 and the J2 connector. If 12 VDC is not measured continue testing.

4.Connect the positive test lead to Wire 167 with it connected at the Start Run Stop Switch (SW1). 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 mea- sured, repair or replace Wire 167 between SW1 and the TB1. If 12 VDC is not measured continue testing.
