Here's how my problems started...while dry camping, ambient temps at 40... I set my heat at 50 in the coach over night......by morning, 11.9 volts at the chassis....heat came on a couple times through out the night...not enough draw to cause this...battery's should have been at full, or close... but, before hitting the sack I look at the monitor...after driving for hours, as soon as the engine was shut off, few led lights had pulled the voltage down to 12.6
..so that told me SOMETHING WAS WRONG!!
