The battery charger turns on when you have shore power connected and your battery turned off. The meter is showing that your battery is drawing 15 amps. The water heater just uses heat from the engine to help rise the temp in your water heaters. As for the fuel petcock take the hose clamps off and look at the valve.
I think you should be looking around for an owners manual and start reading...
