Hmm, no response. I wish I knew something about this model but here's some suggestions. The frig, AC, and microwave are all 110v and the lights are 12v. Is there a converter box somewhere? This is a power converter from 110 to 12v? Do you have a water pump? It would be 12v also and if it doesn't work you could have a problem with the converter 12v system. There could be 12v fuses in there as in newer models. If there are only a few lights there could be one fuse for all of them. You changed a lamp? Could there be a short in that fixture or a disconnected wire in the converter. Maybe a 12v ground wire is loose. Good luck.
