For over a year my accessory electrical has been intermittent on my 2007 Larson Escape and I've been chasing it since it started. It's finally consistently not working and I'm at a loss. I have 12.8V at the master switch, and at the bus behind my counsel, and at each accessory switch; however when I flip any accessory switch (radio, bilge, nav lights, blower, etc) the voltage drops to 0.0 across all accessory switches and at the bus. When I switch the accessory off again I can watch the voltage climb back up to 12V in about 30-45 seconds. I should also note that regardless of voltage drop, I always have 12V at my ignition.
Any ideas what might be causing this or where I should start looking for the issue? Going to bring the battery in to get tested, but it was brand new this season.
