Recently i saw a decline in battery power, coach as well as Chassis. I replaced the Chassis batteries which still did not cure the issue.
The problem i was having was that slowly but surely my battery's where draining while i was connected to shore power. Now battery's are dead and its not even acting like I have shore power connected.
Any suggestions what it could be? I looked at all the fuses I could find but none seem to be bad. I cycled all the breakers but nothing. No power is hitting the power panel. Can't start the generator because batteries are dead.

Thank you

Lou
