Converter question
The converter wasn't working so I pulled it out of the pop up camper. It turn out that the fuse holder was loose so I fixed it. Now it working but it outputting over 15V DC. Is that normal for th...

Your meter is reading it wrong. Looking at the photos of the converter I do not see anything that looks like a filter cap. (There is a small yellow thing that might supress RFI a bit but no way is it big enough to do serious filtering) thus supply is putting a mixed AC/DC with an average value of around 13 volts, but your meter is reading the peaks...
Just an FYI, a DC meter reads average voltage values.
The average voltage for a full-wave rectified, unfiltered, sinusoid input voltage has the following equation:
Vavg = 2 x Vpeak / Pi
So the peak voltage would be almost 24 volts for an average value of approximately 15.24 volts.
The capacitor is on the AC side, so it is not polarized, and like you said does not filter the output voltage, but the battery will.
