brake lights inoperable
Do you have trailer wiring? Look for a short or corrosion. Also check fuses and brake light switch.
Check voltage and ground for the lamps, you can see the fuse. The high mount brake lite and the lower brake lites are wired differently.
yes I have a trailer wiring the grounds checked out. My book schematic does not show a stop light relay as this schematic does. Where is it located? There is a box mounted to the frame with wires from the harness running to it. That may be it ... raining now so I cannot take a pic to post ... There is no power to the brake lights. The top center light works. New brake switch, checked continuity checked prior to instillation.
