With my Intellect off the engine batteries still go flat-no power. This is on my 2000 Sportscoach with 300 cummins diesel. The batteries are only little over a month old so the problem is the red wire probably #8 that is drawing power from the batteries when hooked to the batteries. To keep the batteries charged I have been disconnecting this wire while plugged in to shore power. Of course, if I need to use the awning or start the engine I have to re-connect the red wire. I've tried tracing the wire but get lost when it gets mixed in with the group of wires going into the engine compartment then it is nearly impossible to continue tracing.
I have the VDU re-installed now after soldering some connections and it appears to be working fine now. Thanks for all the input to correct that issue and hope you have a solution for this hot red wire. Otherwise, my plan is to attach it to a d/c switch and turn it on when needed.
Thanks for all your assistance and understanding of my issues.
