Actually probably gonna need a lot of help over the next few months. My 1989 Suncruiser (Itasca 34' A) was kinda drowned in a river last March/April. (Long sad story) Just finally got custody of it. Now to fix all that's wrong. First problem - have B-W Mfg. 45 amp power converter. Are they still in existance, where and are parts available. Is there a wiring diagram available for this thing. I have 120 power ok, won't know until lights dim if I'm running off of batteries or if converter/built in charger is working. Fan worked at first, but now doesn't seem to be working, I have cover off - is there a heat sensor that either is not working or it isn't hot enough 'cause I have the cover off. Why are my 12 volt lights dimming and flickering and what is the clicking noise I can hear coming from the unit. HELP!!
