Sigh.....and the house batteries are dead again.
My Freightliner dealership recharged them. While the house battery disconnect is in the off position there is a parasitic draw of ~ 0.3 volts.
Called my dealership....they said this was normal....not trusting the guy I spoke with I called Thor and they said this was NOT normal, there should be zero draw when the house battery rocker switch is in the off position. No surprise.
Thor gave me gave me a strategy to find that problem. Go to the 12 volt panel and pull the fuses one-by-on, while monitoring the draw on the battery. I'll give that a shot.
As a side note I had the chassis battery disconnected during this time time. I wonder if there is a feed into the chassis from the house battery through the bi-dir relay?
