I was under the hood looking at a few things and it dawned on me that I couldn't find a heavy ground wire on the engine. Typically the battery ground cable is on the engine. My battery is in the trunk. The ground for the battery is going to the frame back there.
There is a light (#14 wire) on the intake. It must be getting a ground through the motor mounts (rubber?) or the braded hoses. It has braded hoses for power stearing, a remote
oil filter, and the fuel lines (EFI return system). The idea of the fuel lines carrying the 500 amp draw by the starter leaves me a little unsettled in the stomach.
What is the best solution? A sort heavy wire from engine to frame, or run it all the way back to the battery?
Any stranded exterior grade wire OK, or some special wire needed? I guessing about 00 coper wire?
