Low voltage at atwood rv heater, help please
I am getting a low voltage reading at my heater. I am testing it with my voltmeter at the blower motor. I get a 10.6 reading when plugged into shore power. Furthur testing at the rv power distribution...

Your battery, converter, and supply wiring are all parts of one 12V system. You need to find out if the converter is working and if the battery is usable.
With a voltmeter, measure across the two battery terminals without the 120V shore cord connected to a supply. You said you have 12V but I would check it again. If it is 12V, that is less than 50% charged. Next, connect to shore supply with your shore cord and measure again across the battery terminals. You should measure at least 13V. If not, there is a problem with the converter, open fuses at the converter, or a tripped circuit breaker between the converter and battery.
Initial diagnosis is that your converter is not outputting charge voltage. Check the 120V circuit breaker that powers it and measure for DC voltage at the outputs.
