I recently replaced the battery since the old one was "cold weather dead." After disconnecting the old one and connecting the new one, I attempted to crank the car. Put the key in, turn to "ACC" and the accessory get full power power. Turn the key to "ON" and all dash lights come on and cycle as they should. Turn the key to "START" and all power is killed and will not come on. turning the key back off or even removing will not restore the power. The only thing that will restore power is waiting a while with the doors closed or disconnecting the negative terminal and reconnecting. This immediately restores all power to all functions until attempting to start the car again.

The battery is good and the terminal connections are good.

I am stumped.

Thanks,
