no blinkers
Hi all,
The blinkers went out on my 78 yesterday. Put a new flasher in, no dice. The 4 ways work but that's about it. Whe I put the brakes on with the turn signal (left or right) that side goes out completely. Any ideas as to where I should start looking?

There are all tied in together.
Signal light switch > Both Flashers & Brake light switch.
Which flasher did you replace?
The Hazard flasher is on the Fuse Box
The S/L flasher is up under the dash on the left wall near the fresh air vent.

there seemed to be 2 flashers. One was stubby and had 2 prongs (the one I replaced. the other looks the same but is alot longer. Both are hanging under the dash about where your left leg would be when driviing.

Turn the hazard light on.
Feel both flashers > You should feel the clicking.
The other one is for the T/S's.

Well the brake lights use the same bulbs,wiring grounds etc as the signal lights. So my geuss is that you either changed the wrong flasher unit or the one you installed is also dead.
Swap the two flasher units, like mil1ion eluded to, and see if the signals work and the 4 ways dont.
When you turn on the signal light to say the left side that prevents the left brake light from coming on, do to the internal workings of the turn signal switch.
Wait a sec........doesnt the turn signals use a different fuse than the brakes???? Damn work thing all my diagrams are at home
And it is the middle of a graveyard shift and my rememberer is tired

Well I kinda remember the wiring diagram on those old things. The wire to the flasher comes from the fuse box and goes to the flasher. Both sides of the flasher should be hot (grab a test light) then they dive into the turn signal switch. Also a hot goes to the brake switch and dives up to the turn signal switch. The wires split off from the turn signal switch and go to the front lights and back lights. So see if the flasher has power at both sides the turn signal switch is pretty much a switch to ground to overload the flasher and make it work. Flasher are nothing but weak circuit breakers with fast resets. Also check the ground to your lights in the back, most sockest have a wire grounding to the truck a weak ground would make the bulb light poorly or not at all and the flasher won't work at all. If you get lost back there the colors are (brown-tail lights) (yellow-left) (green-right) (white-reverse). If you put on your turn signals and have no power to the back on either side and the wiring looks fine and the flasher has power on both sides the turn signal switch is probably shot.
Good Luck

Flashers work for both turn signal and hazard lights. I swap them sometimes to test one or the other.
If you have done that and checked bulbs, find a new column switch from the junkyard. You have to pull the steering wheel.

No turn signals
My 82 Bronco has same problem, no turn signals but flashers. I'll check grounds, believe it has 2 flashers, one rectangular, haven't been under the dash in long time. It's been sitting 6 yrs, need to get it inspected
