So I just picked up a beautiful 68 sport fury, 383 dual quad motor. Very good running and driving. However the brake lights dont work most of the time. They work every once in a blue moon for 5 stops then nothing again. I also noticed the hazard lights are also inop.
Im a mechanic by trade, but, Im a litle stumped on the wiring of the system. Any theories to the root cause? A hazard switch isnt easy to come by, I dont know if its related to the problem though.

change the brake light switch first.. thats the most likely place to fail intermittently..

you could have a fuse issue.. or a power supply issue..

as brake lights and hazard flasher power are usually supplied by the same fuse..

turn signals are on a different fuse and flasher..

from the hazard flasher to the turn signal switch is a white wire..

power from the fuse box to the brake switch and the hazard flasher are pink and from the second fuse from the left in the fuse block.

the power to the 2nd and 3 fuse from the left are supplied by the red with a tracer wire from the splice in the black wire to the amp meter...

that comes from the back of the alternator.. via the bulk head connector. but also thru the amp meter.. so you will want to check those contact also..

clean the fuse clips...  with the battery DISCONNECTED please...

there is a small chance that your turn signal switch is bad..

but check the white wire going into the turn signal switch.. thats directly from the stop light switch..    

the hazard output wire is RED.. and that goes directly to the 4 pole hazard switch..

why not disconnect the battery so there is no current flowing.. turn the hazard flasher on and off perhaps 50 or 100 times.. this may clean the contacts ...

this does not work with the battery hooked up as you are just adding to the carbon as you make and break the contact..
