Well I have pulled most of the tests mentioned here.
Charged the batteries about 2 hours and then unplugged shore power. Batteries went to 13.03 v and slowly drop to 12.76 in about 10 minutes. then it dropped to 12.67 after another 30 minutes. It hung around 12.67 for around 45 minutes and I decided to just time it and see how low it would go. All cables and lines were hooked up as should be! After 4 hours it dropped to 10.66v. I hooked shore power back up and started recharging the batteries.
about an hour and thirty minutes I left everything going and pulled all of the fuses out that was mentioned above. The fan continued to run and charge the batteries. I then disconnected the shore power and it went over to house batteries but I didn't have any power inside sense the fuses were out. I started adding fuse at a time and noticed no add drop to the meter. it was dropping about 1/10th volt every minute or so. I added all fuses back in one at a time and continued until I had them all replaced.
Seen no difference in voltage drop in batteries but again they has gotten down to 12.66 bolt during my fuse installs.
So I left it as it was with no shore power and in about 3 1/2 hours it went back to 10.67v. I plugged it back in to recharge batteries.
I will probably get them out tomorrow and have them tested again. I have a feeling some of you are right that one or both of the batteries are bad!! I hope to find out tomorrow or Monday!!
I post as soon as I get info.

Thanks for all the input!
