I may be telling you something that you already know.
When I was having this problem I was trying to keep my batteries charged up, and kept the motorhome plugged in to do this. Well, here is the trouble with that, if your use/store switch is in the store position the batteries will not charge, if you put it in the use position the power is on the radio all the time and it will eventually burn out. I have put battery chargers in to keep the batteries charged and not burn up the radio.
I hope this information might help someone.
