Your explanation is a little confusing. But, first of all, Your two battery disconnect switches are for your COACH battery and your Engine battery when you are storing your RV, so the batteries do not get drained over time.
Your Power Control Panel utilizes your COACH 12-VDC battery to operate, and it senses whether there is SHORE power. If so, when you start your generator, this panel will control some solenoids that make sure that you never have both Shore power and Generator power at the same time. My best guess is that your COACH battery is NOT fully charged, or may not be getting charged. You should make sure that this battery and charging system is operating properly first of all.
