Battery draining issue

I'm having an issue with my battery constantly draining when i try to start it.
The volt meter reads about 12 when I first attempt to start it. As soon as i turn the key and the engine starts cranking the batery immediatly drains.
Anyone else have this problem? I had the battery and alternator checked and there still good. Any help on this situation would be greatly appreciated!

Definately sounds like a dead cell in the battery, but if your 100% confident in the battery load test then my next move be to load test the starter, could be the starter windings have a resistance breakdown, I've had this happen before on a ford starter had a breakdown in the winding insulation, it would do just as you describe but only when hot, once cooled it was good. If I shut down while hot I always knew I would be staying awhile LOl.

I think when my starter was failing it was drawing lots of power it would kill the battery, in fact it made my + battery clamp go much darker than - and i replaced them at the same time.

I would try a brand new battery and see if that fixes it.

I'm experiencing something kinda similar...

http://www.jeepforum.com/forum/f13/p...ttery-1470488/

One piece I left out of my thread was that the last battery I returned indeed had a bad cell. What would cause a battery to lose a cell?

Charge up the battery fully, then load test your battery disconnected from rig Should tell you if it is good or bad.
