Did you have a battery connected when you were doing this voltage measuring? If so, your measurements of 13.1 were probably from the power in the battery.
AFAIK, removing the polarity fuses from the converter, disables any output from the converter. Where are you measuring for voltage at the output of the converter?
5., I have no idea unless the bad cells in your battery ceased to pass voltage at that time.
You do not have to worry about or try to measure any "over current" conditions at this time. For some reason your converter is not working and that should be the focus of your troubleshooting, Since you have adequate AC voltage coming into the trailer and all your circuit breakers are on (they are all untripped aren't they?), it would seem that the converter has failed. You can confirm this by connecting to shore power and place one meter lead on one battery terminal and the other lead on the other terminal. If the converter is good, it should measure 13.5 V or more. The only other thing to check is the fuse or circuit breaker close to the tongue of the trailer it may be in a plastic box or attached under the frame of the trailer. If that circuit breaker near the tongue is tripped, the battery can't deliver any power to the distribution panel. If you were measuring voltage at the panel, disregard this as it is working.
Are any of your 12V devices working (lights, water pump, stove fan)?
