Talked to the dealership where I bought the battery today. They have another in stock and I asked them to check with Yuasa for the manufacturer date. They open again Tuesday and I'm bringing my battery in for a load test. I suspect it's the battery because the only time it wouldn't start was when I had the ignition on for 30 seconds before starting it. Still it seems strange. It's ok overnight, there's only a 0.7 ma drain, all the accessories are switched through a fuse box keyed to the ignition, the alternator voltage seems fine. I'm guessing a marginal cell. I may be moving to a Li battery.
The voltage between the terminals and the positive to frame are the same. I'll do the voltage check described in the service manual.
