7. Connect the negative meter test lead to frame
ground.
8. Set the start-run-stop switch (SW1) to START. 12
VDC should be measured.
a. If 12 VDC is measured, replace wire 167
between TB1 and the J2 connector.
b. If 12 VDC is not measured continue testing.
9. Connect the positive test lead to wire 167
connected at the start-run-stop switch (SW1).
10. Connect the negative meter test lead to frame
ground.

3. Connect the positive meter test lead to wire 229
removed in step 2.
4. Connect the negative meter test lead to frame
ground.
5. See Figure 4-46. Set the start-run-stop switch
(SW1) to START. The meter should read
approximately 1.0 VDC.
a. If the correct voltage is indicated, stop testing.
