Thanks for the clarification, WhiteTiger.

So, just call me Black Cloud, the Idiot! Wrong battery combined with deceptive wiring are the culprits. After everyone's good suggestions, I dived into the wiring arrangement and found what I thought was the positive cable wired up to a star ground and what I thought was the negative going to...

Thanks, GreenvilleJay. It's a DieHard 51-2. 51R-2 didn't have the posts on the correct side. I was worried about polarity as well, but definitely have +12.5V at positive terminal.

Sure appreciate your helpful comments on high loaded resistance, Mark. I did everything with a voltmeter under no load, so I could be misguided. Given that this is a new battery, I imagine the primary candidate for excessive load resistance would be at the battery cable connections. Would you...

Thank you for the schematics, WhiteTiger. Please forgive my ignorance, but what are these circled items representing?

Thanks for the question. +12.5V across the terminals from positive to negative. Given the weird fuel gauge behavior, I had wondered about the polarity as well, but couldn't see how it could somehow become reversed.

Hello, all After overwintering with the battery disconnected, first attempt at restarting this spring was unsuccessful. Glow plug lamp was faint and fuel pump sounded as if it was struggling. After multiple attempts, I tried to jump the starter, but it didn't even engage. Given the battery was...
