Battery holds a charge for about a day then dies. Alt is good! Something keeps drawing it down. Any help would be appreciated! FYI I have a new battery and an old one that checks out fine.

 

well, you have to hook an ammeter up to it to figure out how much current it is drawing, then start pulling fuses one by one till that draw goes away, that will at least give you the general location of the fault, further isolation would require a circuit diagram and some know how

 

Thanks, I will try it.
