I recently bought a 2012 Bennington Q2575. I’m having an issue maintaining power to the accessory switches and all the switches on the dash. My Master Power switch always has power and is on. But the rest comes and goes in very random intervals. One thing I also notice a lot is when the radio is turned up really loud it tends to kick is off and on repeatedly. I have 2 batteries, and I’ve tried switching from 1 to 2 and even to 1&2. Batteries are good, terminals are good. Fuses are good. Has anyone else experienced this or have a recommendation for me to check? Thank you!
