Coach Fluorescent lighting

I am having a problem with the two fluorescent lights in the coach section of my 2001 Itasca Suncruiser . The wiring diagram doesn't show them so we are asking for guidance on this problem The two lights are ceiling 15 inch fluorescent lights operated by a switch above the switch for the hallway light fixture. Any and all help would be deeply appreciated.

I followed this video and replaced all 3 light fixtures, more energy efficient and brighter too.

What is the specific problem? Do they not light up at all? If so, it could be that you need to turn on the wall switch and also turn on a switch on the ceiling fixture itself. Is the problem "buzzing" or slow startup? This might be fixable by installing new bulbs. Have you checked for electiical power at the fixture? Folks on this forum can offer a lot of help if you can provide more specific information about the problem.

Good luck, and maybe I'll see you down the road.

The problem was not turning on at all. Wiring diagram did not show the fixtures at all. On other advice found faulty wall rocker switch connection. Cleaned wire lug and all is well
Thanks for everyone’s advice and suggestions
Safe travels!

It is probably the ballast. Replace with LED and eliminate the ballast.

first you change the bulbs. Then you change the ballast. Then you replace the fixtures. Before you go thru that replace the fixtures with leds.

I removed the bulbs and ballast and installed LED self adhesive strips.

I ran into the same problem and just as John Hilley suggested, IMO, the best way and the cheapest way to fix your dead light problem is to:

1) Remove the ballast, so you only have 12V going to your ceiling lights.

2) Buy the 15" fluorescent bulbs designed for 12V applications. And you are done!

Note: That ballast takes 12V-DC and steps it up to 110V-AC, but with today's LED bulbs you can find both 12v and 110v bulbs. Therefore, be sure to buy the 12V type if you cut the ballast out of your light fixture.

This installation is simple and anyone can do it if you understand the principles involved. (See attached .pdf for all the information you need to know about this fix/upgrade.)

*** LED USE LESS POWER TOO, but you may find the Daylight is too blue (cool) so I recommend using warm light bulbs in the kitchen/bedroom, and cool light bulbs in the living room/bathroom.

*** You also do NOT have to convert your entire coach in to an LED bulbs, but I would change those lights us use most often; and then only replace the other bulbs when they fail. After all, if the light switch is turned "OFF" then an incandescent or fluorescent bulb uses just as much battery power when you are boondocking as an LED bulb!
