Step 6. Check for +24 VDC between wire 462 (8) and ground at turn signal lever (9).

If +24 VDC is not present, repair wiring 462 between hazard

warning switch and turn signal lever.

If +24 VDC is present, go to step 7.

Step 7. Check for +24 VDC between wire 463 (10) and ground at hazard warning

switch (1).

If +24 VDC is not present, replace hazard warning switch.

If +24 VDC is present, go to step 8.

Step 8. Check for +24 VDC between wire 463 (10) and ground at relay K3 (11).

If +24 VDC is not present, repair wiring 463 between hazard

warning switch and relay K3.

If +24 VDC is present, go to step 9.

Step 9. Check for +24 VDC between wire 464 (12) and ground at relay K3 (11).

If +24 VDC is not present, repair wiring 464 between turn

signal lever and relay K3.

If +24 VDC is present, go to step 10.

Step 10. Check for +24 VDC between wire 445 (13) and ground at relay K3 (11).

If +24 VDC is not present, replace relay K3.

If +24 VDC is present, go to step 11.

Step 11. Check for +24 VDC between wire 445 (13) and ground at brake light diode

(14).

If +24 VDC is not present, repair wiring 445 between relay K3

and brake light diode.

If +24 VDC is present, go to step 12.

Step 12. Check for +24 VDC between wire 443 (15) and ground at brake light diode

(14).

If +24 VDC is not present, replace brake light diode

(page 4-168).

If +24 VDC is present, go to step 13.

Step 13. Check for +24 VDC between wire 443 (15) and ground at connector K (16).

If +24 VDC is not present, repair wiring 443 between brake

light diode and connector K.

If +24 VDC is present, go to step 14.
