Help! I have a 2009 Winnebago View on a 08 Sprinter chassis. Recently I noticed that my chassis battery was draining quickly during storage. Through some troubleshooting with my meter, I discovered that I am getting voltage from the chassis battery to the boost solenoid even with the engine off so that the solenoid is always closed linking my house and chassis batteries. I recently replaced the Y cable, the chassis battery, the boost solenoid, and the boost switch. I traced the voltage back to wire KE2 at the boost switch. Any help would be greatly appreciated.
