this alarm came on not last time out but the time before. I thought it was because the batteries were low so we went back in and put the batteries on the chargers and fully charged them. we went out yesterday and the alarm is still there. Both batteries are fully charged right now, 12.7 and 12.78V, and when I turn on the house battery and press a conext button to turn it on the alarm comes on right away. I swapped both batteries and it still does it. the little black wire is connected and tight. Any other trouble shooting tips?
