I recently purchased a 1994 Coachmen Catalina and am currently in the midst of making up for lost maintenance. I have found three lights so far that are not getting power. The fuses are all good, and so it is a puzzle how some lights have no power? A wiring diagram would help, but Coachmen did not supply any fuse legend either in the owners manual or written on the fuse board.

Anyone know of a wiring diagram for this model or help me understand what may be the problem?

The first thing to do would be to drop the non working light closest to the fuse box and check for power and ground . Most RV's are wired in the quickest / cheapest way possible , that involves a single wire from the fuse to the furthest load in the circuit, and connecting the other loads along the way with " quick locks or scotch locks " . These devices are quick to install but can be troublesome over time , because they cut through the wiring insulation and some of the strands inside , weakening the main wire that can break over time.
If you have no power to the wiring then you may have a hidden or unmarked switch.

Thanks....a good thought about a hidden switch. There is a switch on the kitchen cabinet under the sink. I thought it was for the water pump, which i have yet to try, since there is no water in the tank. The switch maybe for the light over the sink, which is one of the lights with no power. The owners manual says the pump switch is on the monitor panel, and a second one in the bathroom. I will check this out.

Skip426 - brilliant. The switch on the cabinet has two yellow wires on the output of the switch, which go to the light over the sink and the light over the dinette table. These were two that I thought had no power. The third one is the porch light, but I have not removed it from its mounting to check the incoming power wire....it could be a damaged fixture as I can tell the lense does not fit tightly and will probably not turn water. It has a switch inside the footwell, with night light, which works (labeled porch light).

Thanks again.
