I would start by taking a digital multi meter, taking off the neg. battery cable, hook up the meter between the neg. cable and the neg. battery post, and see what you got. The draw should not be over 50 um amps. If it is, then start pulling fuses until the meter drops below the 50 um, then you know what circuit to look at for repair. The battery should be fully charged up before doing this. Do not be turning anything on during this process.
