CHASSIS ELECTRICAL (CONT)
BRAKE LIGHTS DO NOT OPERATE (CONT).
Step 6. Remove screws, lock washers, cover, and gasket from junction box. Using a multimeter, check resistance
across resistors with brown wires attached.
If 4 ohms ± 1 are not measured, replace resistor (page 4-65).
Step 7. 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.
