This is a simple test that will tell you if your charger works. But not how well or efficiently the charger works. Unplug your shore power and run the furnace blower for 2 minutes to pull any surface charge off the batteries.
Put the volt meter on DC volts. The DC volts symbol looks like a solid line on top with a dotted line under it. If there are multiple selections for DC volts then put it on 20v or the closest reading that is more than 12.
Measure the voltage at the batteries. Then plug the RV in and measure the voltage again. If the voltage increases you are charging.
finally an accurate post.
Looking for 14+V when charging is NOT repeat NOT a good indicator. Battery voltage won't reach near 14V until it is fully charged. Voltage could be as low as 13V on initial charge depending on the charger and battery. And the typical WFCO charger will almost NEVER get to 14+V, maybe 13.8
