View Full Version : Hazard / Turn Signal Issue

Need a little help with the turn lights and hazard wiring?
My hazard lights will not work unless my indicator switch is turned to either Left or right sight. All other light functions, brakes, headlights, taillights, and turn signals work as they should.
I have the Ron Francis harness with the FF gauges.
Any thoughts or suggestions would be appreciated.

How did you wire the hazard switch? You should have both pink feed wires on the two center pins and the other wires (left & right) on the two pins on one end of the switch with the other end empty.

Papa,
Yes that exactly what I have, I referenced one of your pictures from an earlier post. When I replace the pink wires with the power feed from the indicator switch they work!!

Check the hazard fuse? You should have power on the hazard pink wires at all times. I'm not sure which fuse they go to in the BATT FED portion of the panel, but there are only four to check. Also, try swapping the turn signal and hazard flasher pots to see if it could be a bad flasher.

I did swap the fuses, checked for power, both good. Do you know if there is supposed to be any ground on the hazard fuse?

You don't need to add any additional grounds. All the circuits in the panel are grounded once you place the ground wires included in the harness.
Something isn't adding up here. As Papa said, the pink hazard wire is a battery circuit so is powered at all times. The turn signal wire is only hot when the key is on. Other than that, they're exactly the same and shouldn't be any difference in how they work. What's suspicious though is when you remove the turn signal wire and put on the hazards, yes it works but I'll bet it's working because it's disconnected from the turn signals. That would suggest backfeeding somewhere. Nearly every issue with turn signals and hazards I've seen are due to the hazard switch not being wired properly (has to be EXACTLY like the diagram), or some other path like the indicators. Do you have +12V on the pink hazard wire? Should be present with or without the key on.

If I understand what you're asking, the flashers (big silver canisters) provided with the kit work fine and you don't need the style with the ground wire. If you have power on the pink feed wires (both of them), and the 4-ways aren't working, then you need to start tracing. Is the switch good? Are you using the DPST (6-pin) switch that came with the kit? Maybe try to swap to the other side of the switch? Have you tried to power the left/right wires directly (bypass the switch)? Are you using the provided bulbs or LED bulbs?

Do I need to have my gauges hooked up in order to test indicator and hazard switches?

If I understood Chilly correctly, he has LED bulbs and he is using then indicators built into the gauges. I mentioned the ground on the flasher because all of my LED flashers have a ground pigtail that must be grounded to function properly. I think the indicators and gauges need to be hooked up but could be wrong.

I'm really having a difficult time understanding what the actual problem is. So, let's try to start with the basics:
1. Did your kit come with LED bulbs or did you swap over to LED bulbs?
2. Are you using the flasher relays (cans) that came with the kit or LED compatible flashers if you swapped to LED bulbs?
3. Are you using the kit-supplied turn signal switch or something different? (Russ Thompson turn signal setup, or other)
4. Do you have power to the pink hazard feed wires at all times? (key off or on)
5. If you apply power to the hazard blue & green (Left/right) wires, do the hazard light come on?
6. All bulbs are in place, including dash or gauge indicator bulbs wired?
Test the following and tell us what each result is:
- Brake lights come on when the brakes are applied (key on or off)
- Head lights, tail lights, and marker lights come on when the head light switch is pulled out
- Left turn signal works (key on)
- Left turn signal does not work (key off)
- Right turn signal works (key on)
- Right turn signal does not work (key off)
- Hazard lights work (key on or off)

Thanks for the help, found the problem, was a flasher relay, but unfortunately it was one I replaced an original with and it was bad as well. Go figure. I just didn't suspect 2 bad in a row.
My kit came with LED in the rear and a regular bulb in the front. There is a pigtail that you have to use to get the tail lights to work properly.
Henry turns out you do not need the gauges hooked up to test the switches and the cans do not have a ground wire. Thanks for the input.

Glad you got it figured out. Trouble shooting can be tedious at times, and you can never rule out anything until you've exonerated that part of the circuit.
