This is 3rd part in the series of Electrical things both 120 volts AC and 12 volts DC that are checked, today is Power Converter and Battery(ies).

Ok for those of you who are not familiar, there are two electrical systems in your RV:

120V AC – what you would recognize as household electric, this takes CIRCUIT BREAKERS, just like in your house.

12V DC – battery electric, like in your car/truck, these take FUSES.

Ok, checks, 33-36 we check out the converter to make sure it is working, 37-44 battery/batteries are checked.

Next week we will check out generators.
