connector (2).

If +24 VDC is not present, go to step 4.

If +24 VDC is present, go to step 2.

Step 2. Remove two bolts (3), lamp guard (4), mount (5), and lamp (6).

Step 3. Check for +24 VDC between wire 42HL (1) and ground at socket (7).

If +24 VDC is present, replace lamp.

If +24 VDC is not present, repair wiring 42HL between socket

and auxiliary headlight connector.
