I have a 2011 alpine 3450rl. My converter is in the space behind the fuse/circuit breaker panel. You actually have to remove the entire panel to gain access to it. The reverse polarity fuses are plugged into the back of the converter. The transfer switch you had installed is for the generator, even though you don't have one installed. All it does is determine which source of A/C voltage enters the trailer, either generator of shore power. That switch has nothing to do with DC voltage. Since you had an issue with shore power at the pedestal I would suspect the fuses on the converter as others have said. In a worse case senario the converter itself may be fryed. With an issue at the pedestal there is no telling what other damage may have happened.
