grounds in headlight bucket

[azr]

Does anyone know the purpose for the grounds coming from the headlight bucket nuts on a 79' 750L? the turn signals require the 'usual' ground wire in order to work, so I don't understand what these 'extra' grounds are for. Some enlightenment would be greatly appreciated.

Not sure what "extra" grounds you might have.

Yes, the signals have their grounds on their mounts, but somehow, there needs to be a reliable connection to a chassis ground. Since the signals are essentially connected to the bucket (via the mounts, the bucket needs a good ground, too. You just can't rely on the bearings to maintain a good ground, you need to use wires.

I'm used to the signal grounds being on the mounts, then connecting to the wire harness in the headlight bucket for sure, all my other bikes have that but none of them have these extra grounds coming from the headlight bucket bolts



GSX1000 mentioned it might be that the lights are running lights.

GSX1000 mentioned it might be that the lights are running lights.

If you have running lights, you will have two wires running through the stem. The ground still connects through the extra wires.

After you posted that pic of the headlight, I checked the parts fiche and the turn signals on THAT model go into the metal bucket. So, the stock front turn signals, for that model, would probably only
have one wire coming from them and use that washer as the ground to the stalk, no?

Like so...

Again, as I was eluding to before, the front turn signals that you have were not stock on that model. All of the '82-up T/S with the front running lights have two wires and the ground ring.

I don't have running lights then, the front signals are the same as most, one wire coming from the bulb and the ground the typical separate eye hole attached to the mount. One difference between this bucket and the others is that is is metal VS plastic.

They have separate ground wires because the turn signals are by OEM design rubber/plastic mounted and electrically isolated per ground. A continuity check between the headlight bucket and the light socket "ground shell" should confirm this.
They would be insulated ,isolated without the special wire and lug you see. The special wire lug connects to the nut,and the metal stalk and thereby to the light socket's ground shell. You need it.
