First off, quit removing your battery leads with the car running. That is a sure fired way to ruin your alternator and CDI module.
You need to get a volt/amp meter and start pulling fuses to find out which circuit is causing the drain on your battery.

You need to see if your alternator and voltage regulator are working. Get a voltmeter and check the battery with the engine running. You should see 13.5-14.5 volts at the battery.
