Also, the "test" cluster in which the gas gauge did work, had previously been re-soldered by me. That may be why that circuit of it, at least, did work.

I never did correct the charging issue with that other car with this cluster. There's still something bad lurking in it.

I was thinking I would re-solder this cluster and see if anything behaves better. I may have access to another car for troubleshooting as well so might try a good car-bad car swap with both.
