OK, so I finally got back to the 5er from about 10 days ago. I charged the battery then and disconnected the negative wire on the battery. It was still fully charged, 12.84 on the multimeter after about 10/11 days.
I hooked up the negative wire to the battery then turned off the battery switch and opened up the fuse box and started removing the 15 amp blue fuses and checking each one as curt12914 said to do.
There were 10, 15 amp blue fuses. 9 registered 0.0 on the meter. One registered .35 on the multimeter. I guess that is .35 volts. This is the fuse marked TV / Radio. There are 2 flat screen TV's and a Radio/DVD/DVS player in the 5er.
When I check my meter on a new AA Battery it registers 1.57 on a 1.5 volt battery.
So my fix is to just leave the 15amp fuse out of the TV/Radio slot. Replacing the fuse takes 2 minuets. I can plug the 5er in as there is 50amp service, but until I am going to use it, I leave it unplugged. Why have power to the power center/converter charger with the fan coming on & off, along with the invertor & fan on & off. I just didn't want the battery going dead every week or 10 days.
Thanks again curt12914.....
