Converter or Inverter (they are different)



If your battery is depleted, it cannot provide the power "IF" the converter is also not functioning when connected to shore power/generator.


I would also suggest checking to make sure the converter is operating by either making sure it's circuit breaker is not tripped and/or the reverse polarity fuses (up to 3 total) are not blown. These reverse polarity fuses are there to protect the converters electronics should you connect a battery backwards, but we have also seen them blow when there is an inrush of current from the converter trying to recharge a depleted/bad/faulty battery sometimes. The converter is also a battery recharger when connected to shore power/generator.


As Cavie pointed out, these fuses "can" be on the converter., but many are also in the RV's distribution panel..depending on make/model. See pics below:

All fuses and breaker are good. The converter puts out 1 V..measured right on the lugs on the converter itself...assuming bad converter?

The converter inputs 120 volt AC and outputs 12 volt DC.

Just to be sure, which kind of voltage do you have the multimeter set to measure, if it's not an autoranging type multimeter

Remove the negative wire from the converter & remeasure output of the converter. If you still get 1v DC with no load, then your converter maybe bad.
