I have a 2004 Safari Zanzibar (Class A) Monaco mfg. I turned on all the 12 volt interior lights and after 20-30 minutes the overhead florescent lights and the passenger side lights suddenly went out....
Melvin AT Monaco was very helpful. He suggested that I "jump" to breaker to determine whether that was the problem.. I did and it was. All I have to do is replace it. Thanks for all the help. Rush
