All of a sudden I have no right rear brake lights, turn signal or hazard lights Tail lights ok Bulbs good ground good Left rear and fronts everything ok
Not getting any voltage at dark green wire at plug connection pictured Checked yellow wire that goes to left side and it blinks test light hazard, turn signal and study 12 volts brake light

Ran jumpers from extra battery 12 volts to other side of green plug Right Lights up all bulbs as it should Thanks for any help I can get

 

Check that same wire at the plug on the steering column. If it doesn't blink there its probably your directional switch.

 

So far you've done a great job of troubleshooting - you've shown that the problem is not in the tail light housing or it's wires. Just don't stop there. Keep checking each connector in that wire up to the dash until you find the problem. Same process with the test light on the terminal.

 

Found Problem Ground Issue at Speedometer cluster
Coming from the bottom steering column with the hazard switch on I found the yellow wire that goes to left rear Stop Hazard Turn Test light blinked as it should Dark green wire Right side Stop hazard turn signal (Problem Side) Blinked ? ???? Still no lights at right rear.
Took gauge cluster cover off and saw where I ran a ground wire to tach screw that mounts it to make factory tach work years ago Put jumper wire from it to speedometer cluster screw and solved problem
Thanks for your time to help figure this out Thanks
