Hi Mike - I like the 12V battery test concept. One question... for those of us with motorhomes, where the CHASSIS battery is likewise connected to the frame, is this still a "useable" test? I am presuming so, since the test lamp is connected to the HOUSE battery, but figured I'd run it by you! Thanks, as always! Scott
Yes, both the chassis battery and house battery bank will be grounded to the chassis, so either positive battery terminal will provide a test fault current to confirm continuity under load.
Also, in the bulb test, since more current is desirable, would it be worthwhile to put 2 bulbs connected in parallel (in some sort of mount for safety), or would that just confuse the voltage measurement?
Great article Mike. Do you think that while you are at it, that turning on a high draw appliance like an air conditioner or a space heater and measuring the AC voltage ohm the neutral line is a good idea? The voltage between the neutral and RV ground point should be near zero volts AC and there is an issue if it isn’t.

That is supposed to be like.

Is the Klein RT390 circuit analyzer anything luke/near the ideal?
