Update: I checked for drains by monitoring current draw, then pulled fuses of suspected problems. The second fuse I pulled( cigar lighter ) was the issue. There must be leak to ground small enough not to blow the fuse on that line. After leaving that fuse out all day today, no issues. I'll monitor it for the next few days to be sure that was it. I suspect I'll be needing a new lighter socket, know of a good source?
