What did Volvo Do?

So far, your grounds have lasted a long time.

My pet peeve is the grounds that one may not even notice.

The license plate light on my 544 is instructive - there is no ground wire!

There is a small metal clip on the light socket that must ground to the bumperette,
the bumperette must ground with the bumper,
the bumper must ground with the bumper bracket,
the bumper bracket must ground with the body,
and the body must ground with the battery.

Get the picture?

After I clean a ground and I have time, I like to prime and paint around the minimum size bare area that will do the job. I am considering adding a little dielectric grease to the bare spot.
