CLEARANCE LIGHTS/MARKER LIGHTS DO NOT OPERATE (CONT).
Step 9. Remove screws, lock washers, cover, and gasket from junction box. Tag, mark, and disconnect wires from
resistors. Using a multimeter, check resistance across resistor(s).
If 4 ohms + 1 are not measured, replace resistor (page 4-65).
Using a multimeter, check continuity between pin E on 24 Vdc intervehicular connector and resistor.
If continuity is not present, replace 24 Vdc intervehicular connector (page 4-93).
If continuity is present, replace or repair wire between 24 vdc intervehicular connector and resistor.
