I have an '06 LLY, GMC C5500; in the mornings, for the past 2 weeks, when you start it up, it will run for about a minute, a warning light (looks like a battery) and the bells start coming on, then it shuts off. it will crank back up right after and do this several times. Then it will stop doing it and stay running for the rest of the day. The batteries are not weak. I have 6/6 volt batteries that I had to recently fill up with acid (5 gal.), all 6 were bone dry. I have to plug into an outlet every night because this is my work truck. It is set up to run office equipment and power lights. Does anyone have any suggestions or ideals???
