Had it towed to the house and popped a spare battery in there that is fully charged and it still won't turn over.

Oil and coolant look good. If the Alt seized up would it prevent the car from turning over? When I go to start it you can hear the starter trying to turn and all the light go dim. i suspect that its drawing a lot of juice from the battery but can't spin the fly wheel.

Kinda scared that something in the motor locked up, but with the battery being dead, I keep thinking its something with the Alt as well.

Thanks,

Will have nothing at all to do with the alternator. Even at 11.9 volts the car should crank since that is well within the operating specs of a 12 volt battery.
Have you done anything to the engine? Bone stock?
I hate to say it but I am not optimistic for you with the info that you have given so far.
