It turns out that my Optima is, indeed, dead.
My charger says there is an internal short and I'm fairly sure that's what was causing my electrical issue.

The date on the side of the battery is December 2006. I can't complain. That thing doesn't owe me anything after 10 years.


We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
