Motor help - PLEASE!

You can not tell if a battery is bad by reading the voltage when the battery is not under a load. If you can, check the voltage while the motor is cranking. My bet is your battery is bad and your voltage is dropping way down when you put it under a load.

Agree 100% like some one said take it to Auto Zone they have a special tester there that will pull it down while testing. . Like that someone said a dead cell will still read 12 volts and run some items, but when it takes a load such as turning over a motor it can't hang.

I have a 200 Merc, the starter was going bad, it acted like a dead battery, if the battery is food might be the starter.
