I had the same problem 2 years ago. Good voltage, good grounds even went as far as to replace the starter. The problem was a plate inside the battery seperating under load. Sometimes it would make sometimes not. Drove me crazy for 2 days while on the road until I installed a new battery.
When I turned in the old battery for a core credit, it still showed 12.7 volts. Never tried my battery boost because my battery never even dimmed the lights and never showed low voltage.
I did the exact same thing 4 or 5 years ago. I spent 2 days messing with stuff. People were telling me it was the battery but I wasn't listening. Mine was showing 13.6 volts after charge but the plates were shorted and wouldn't turn the starter.
I put in a new battery this time but the old one wasn't holding a good charge anyway.
