120 Volt System Session 9: Using a MultiMeter

A multimeter is a versatile tool that will allow you to check 12-volt DC power at the house batteries and charging capacity from the converter. On the 120-Volt AC Volt setting it will show proper voltage to outlets, from the campground source, and to appliances. The Ohm setting will show resistance values for testing the refrigerator thermistor and other electrical components. Using either the Ohm setting or continuity setting will provide testing of wiring for breaks or what is called “open” circuits.
