I let the MH sit for a couple of hours with nothing on and the batteries drop to about 12.6 volts. I'm realizing I may have a short or something drawing power when the MH is just sitting there. I have always had this issue with the battery disconnect switch just switching to store mode at about 12.5-12.6 volts by itself. Has anyone had this issue with possibly a bad relay in the battery disconnect switch? If this switch or relay is faulty could it possibly drain down the batteries?
My battery disconnect switch is a-- Intellitec BD1.
Thanks for your replies in advance!!

It sounds like your isolation relay is dropping out, not your disconnect.
The isolation relay cross charges the batteries if there is some charging above 13 volts and it will disconnect at 12.6 volts.
See if you can send some pictures of the relay or relays your talking about.
Your battery disconnect relay may not be working at all. The isolation relay may be closing and supplying all of your power.
