Angry turn signals

ok so I have not been on this site for some time. 2 grand kids and other issues(heart). Got the 69 done with a Summit wiring harness. now all of a sudden no turn signals and lost both break lights. i started with the fuse and flasher still no turn signals. Replaced the turn switch in the steering column..nothing lost any ideas?

Re: turn signals

Well I would trace power from brake switch to intermediate connector under the dash/kick then out to trunk. Check grounds at front turn signals and check the flasher under dash by radio. Do you have working hazard flashers?

Re: turn signals

Rear brake lights and turn signals circuits work in conjunction with each other... something that was unique to American cars and never understood why.
It a pain in the butt setting up trailer light wiring in countries the American system is not generally used... easy trick is to wire for american and use trailer light lens that can be turned over.

u NEED and a volt/ ohm meter and follow thru as Brian suggests above, and without a circuit good diagram u will be banging your head against a brick wall trying to figure out what is going on and what should be....there is a sticky thread here with some very good colour circuit diagrams.
Also a bad ground will do what u describe.

My Spelling is not incorrect...it is creative

Re: turn signals

Brian I lost everything to do with flashers; turns and hazards. if you wanted to turn left you had to reset turn signal. right was fine, then one day I noticed I had solid right turn signal and had to move turn signal lever to make it flash, then everything went. no turn, flashers and lost only left stop. now i have lost both stop lights. replaced fuses in both stop and turn, flasher relay, and the turn signal switch in steering column.

Re: turn signals

Re: turn signals

Should be mounted to the dash support by the ashtray housing and the radio if original wiring or factory spec replacement.

Re: turn signals

Check your bulbs. These old cars act funny if the bulbs burn out or lose a ground... Heck, I've heard of the socket contacts getting dirty and causing problems. That and the grounds in the front light assemblies.

Also, my turn signal switch wires got chafed and cut. I took it all apart, cleaned it, repaired the wire, and put it back together. Might be something to look into. All that stuff goes through the switch, obviously.

Smile Re: turn signals

i do have the diagrams that you sent me along with the Fishers and Summit diagrams. All the bulbs are new and work with the headlight switch as they should but no turn signals or stop lights now.It seems strange that they work right one day and slowly quit working. If it was just the turns I would not have any problems driving it with hand signals but with no stop lights scares me. I have been hit twice in my truck pulling into my driveway so with no stop lights..... I hate to think what would happen with the 69.

on a lighter note we took best car at Roosters in Canton Oh. last Monday. Largest crowd for them at over 275 registered cars.

Re: turn signals

Chris - Okay let me recap and then theorize:
You have parking light front and back. You do not have turn or hazard or Brake lights.

As stated by others above - If true the one common element is the $2.00 plastic brake light switch since the hazard/turn are routed through so the flash will stop when brakes are applied.

You can shunt around the switch with test leads and if everything works as should be the Brake light switch is at fault and is an easy replacement.

Re: turn signals

The brake switch/light circuit is separate from the turn and hazard circuits, as far as power is concerned. They all do go through the turn signal switch, though...
