Wow! I really like the two tone red. Nice Jeepster.

If you look at the case for a while, I'll bet you can figure out how to get the can off without hurting the innards. It may take a couple of slits around the edge of a crimp to get some pry room. I'll bet it's built on a insulation base with the lid just as a cover.

I've done that with the original bimetal oil pressure sensor on the '48. I used RTV sealer to close it back up.

Oh, by the way, on the truck the primary battery leads are red with 3 white tracers too.
