That's right. An easy way to do that is to attach the red (positive end of the volt meter to one side of the Trombetta (located in the right front part of the engine compartment- see picture) and the negative end on any nearby unpainted bolt head. The two big red wires lead to the chassis battery and the coach batteries. With the coach plugged into shore power, read the voltage off of both posts - one at a time. If you get the same voltage, shore power/generator are charging both batteries. If you get different voltage, they are only charging the house batteries. After turning on shore power or the generator, you have to wait for the house batteries to charge above 12.6v before the Trombetta closes to charge the chassis battery. So wait a while to take the measurements after plugging the coach in. Thanks for the help.
