Hunting a battery drain on Fuse #11

[Donald Milton]

My alternator went out, replaced it, drove about 35 miles home, got out and next morning battery was dead. It was about 2 years old, so as a precaution, replaced it. Was OK for a day, talked about potential of bad alternator so got a second replacement for it. Now I am on my second replacement alternator and first replacement battery. Truck sits for a day and night and its a dead battery again.

This time we isolate #11 fuse as having a high battery drain, pull it out and truck cranks up and maintains a battery charge for last four days. I know this circuit, #11, controls the radio. Does anyone else have a list of other applications on #11 fuse and how to isolate them?
