HELP! No Reverse/Brake Lights!

[CJ Girl]

Hey everyone... pop quiz... I have running lights and turn signals on both sides, but no reverse or brake lights... also my 4wd indicator and horn aren't working. Fuses look ok... any ideas?

You could have several things wrong there. Did everything quit working all at once? If not, you will need to look at them one at a time. The switch for the crake lights is actuated by the pedal, make sure that is making contact. The reverse switch is actuated from the Transmission , check the wiring there.

check the ground back near the tail lights.
I would start with a volt meter and check for voltage to ground at the bulb socket.

Also a multimeter test of fuses will tell you if they are good, I've seen ones that look it but aren't good.
