Okay.. that is great news. And good on Kragen for doing things the way they did.

I doubt your battery was fully charged after only an hour... but clearly charged enough to give it a proper load test. So...

Your battery is fine (though try it again in the morning.. a weak battery can and will hold a charge for a brief time, but not necessarily overnight)

I'd say it rules out connections issues.

Bottom line is, when your car was turning over, but slowly and not starting, your battery wasn't charged. ie, you had a dead battery.

That leaves to a bad charging system, or a battery that loses its charge after time. A short circuit; something left on that draws electricity; or your battery doesn't hold a charge because its old.

I'm leaning towards charging system... we know it works if the lights brighten when you rev the engine, but it might not be working properly.
