Looking forward to any ideas
thanks

had the same issue it ended up not being a slow drain on the battery.
the distance between the battery and the alternator made the wire size a critical factor. the alternator wasn't pumping enough juice rearward to fully recharge the battery. between the fans and the msd i was slowly draining the battery driving and i wouldn't notice unless i was starting the car. i am using a one wire alternator, i used heavy guage wire from positive battery right to the alternator post.
just check charging volts at the battery not at the alternator to verify this you should get 13.5-14.0 at the battery to have the battery charge.
just my 3 cents
