No spark and i can only get 5V at the coil.

I put it on the trickle charger last night then took it to advance to do the half hour charge this morning. It tested good at 12.5v but only 523 out of 600 cca's. Gonna take a nap then mess with it some more.

If it spins the engine over fairly normally it has enough juice to make it run. Period. One of those cars will start with the battery nearly dead.
