To sum things up my battery is being drained when the key is off. I am tired to pulling the negative battery cable off so I am starting to troubleshoot the problem. So far I pulled ALL of the fuses out and unplugged the voltage regulator going to the alternator. It is still pulling power from somewhere. I am by no means an expert in this area so if anybody has any suggestions I would greatly appreciate it.

Has it been converted from 6 volt to 12 volt? if so, then you need a special regulator piece going into your alternator. Try unplugging your alternator when you shut it off and check to see if it is still draining. If that doesn't work, get your battery tested.
