I removed this to replace it and as it came off, a small copper ring fell into the engine bay. I retrieved it but now I'm not sure where on the relay it goes. Any ideas?

 

What is "THIS" that you are trying to replace?

 

I'm guessing the "Starter Relay" like the title of the thread states.

 

That is correct.

 

Where's Kramer?

It was a washer that fell off, there was one on each on the larger posts on the starter relay, originally
It was put on last and when nut was tight it should prevent it from vibrating loose, copper was used because it is an electrical connection, but any washer can be used or no washer for now

Its best to use similar metals on electrical connections, dissimilar metals can cause corrosion over time, but we are talking years and years, and moists environments, lol

 

Makes sense, thank you!
