My Real Good toys house was all set with lights - 5 in total. House has sat for a month or two and when I went back to work on it the only one that worked was the set in the bathroom on the 2nd floor at the end of the run on the right. Found the electrical line still active on the first floor but all of second floor to the left side is dead. Everything is still intact as far as I can see. Ceiling and table lamps are all dead. Is there a problem with the transformer?
