Thought I needed a quick battery terminal cleaning. Ended up disassembling and cleaning both posts, hot post, then still chasing voltage drops of 2 or 10 Volts. All well as soon as I r&r main shutoff. Bringing the spare but I think it may have had some dirt between the contacts that I jarred. Can't get it to fail again.
Effective and enjoyable 2hr start to today's festivities!
