turn signal, brake light ground

[Scout-It-Out]

1979 Scout II, 304 v8, 727 trans.

The driver side turn signal works but is very dim. The brake light on that side is also dim. I grounded the bulb housing and the light gets bright. I hate to add a ground wire. I would prefer to repair or clean the original ground.

Where is the ground for the brake/ rear turn signals located. There is a ground screw behind each tail light but the brake light wires don't seem to go to it. I cleaned them anyway.

I found a sticky for wiring diagrams but I didn't see one for my Scout. I have a diagram for a 73 Scout II. Would the rear lighting portion be the same?

Thank you

So I found the problem. One of the aftermarket bulb holders I had in the rear had a loose ground. In all my search for problems it started working! Then I went back wiggling the wires to find out what I did. Who'da thought a "new" part would be the problem!!

I would still like to have a circuit diagram and to know where the grounds are. Thanks!

I kind of thought it might have been the socket itself. I doubt I have any diagrams on hand for the 78-79 yrs. Most of my stuff is pre-75. And they have the metal buckets for both rear light fixtures. That have grounding wire that gets attached to body inside the pocket where the fixture mounts
