No turn signals or running lights but horn, headlights, taillights, dash works

[Tsmith]

So as it says I have no turn signals. Can't get them to come on at all, even just with key on. Everything worked fine until I got a flat rear tire in the middle of nowhere and had to ride another 5 miles to nearest gas station. I turned on my 4 ways and all was good. About 3 miles down the road they all quit working. I have checked fuses by the battery, and all 4 lights. If they came on but didn't blink I would check the relay. They are supposed to be illuminated at all times with key on and blink when the switch is used. Nothing at all from any of them though. Any suggestions?

Bad relay. The light stay on, a second, brighter circuit flashes. Lost ground, lost power from the ignition switch....... We can't diagnose an electrical problem without some leg work from you. Check power to them. Use a schematic and follow the flow to the running light circuit.

It's not a relay because the lights dont even power on. All 4 have power to the bulbs. All the bulbs are good. The 4 way and turn signal switches are on opposite sides. Horn and all other lights work like they are supposed to.

What else do you want me to check?

Umm, obviously not, the lamp don't light up. Grab the wiring diagram and start tracing from the source forward or the switch back. I would check the switch back. Are you sure the fuses are good? I would grab a ten amp fuse and leap frog the fuse with the new fuse.

Using a voltmeter I have power at all 4 bulbs, which would negate anything from the battery to the bulb correct?

[92xjunker]

Are you testing the bulb pins and the bulb neg or the frame?

[Tsmith]

I am testing the lead in on the back of the bulb. I can see the filament in the bulb itself is still good.

Should be two pins, both are +, 1 is running the other is turn, the - is the socket itself. It has a lead attached to it at the base which feed to the harness - .

.... the - is the socket itself. It has a lead attached to it at the base which feed to the harness - .

And that ground is blended in with a few other components to form the secondary ground wire that leads off the battery. Small one, off the negative post. There is a small connector right at the battery and then it goes down to the engine where a case bolt holds it in place.


It's very common for that connector to be the source area... be it the blades inside not contacting well, the connector being damaged, or it just coming apart.


That is where I would check first.
