OK, I was installing a new light fixture in the bathroom which I am renovating. I have installed a new headliner and was attempting to position the new light fixture in a similar location to the previous light.
The mounting pattern is different, the first screw went in fine the second screw caught the aluminum beam, So I moved the fixture over approximately 2 inches to clear the beam. First screw went in fine, second screw almost in and the hall way light that I had on for additional lighting went out.
The 12 V lighting in the front main lounge works fine, however, all 12 V lighting from the bath module back to the rear lounge no longer works.
The outdoor light at the entrance and the switch that controls the floor lighting which is in the same 2 gang panel, is not getting power. I checked the fuses and all appears fine, I think I may have hit a 12 V wire that feeds the fixture in the bathroom with the screw.
I removed the headliner in the bathroom and could not see any obvious signs of damage to the wiring.
What do I do at this point to get power back to the lights?
Any suggestions?
Thanks,
Mike

Need to check your fuses sounds like you hit a + wire...for that circuit... pull last screw out first... check fuses with gauge or test light.. they will blow under caps...

I was just working on that circuit a couple of days ago. Fuse 5 (if I remember correctly) with light blue and double black wire fed the right side front, 2 bath module lights, and the rear reading light.
The porch lamp, galley lamp, water pump, and floor lamps were on fuse 3 with purple wire.

If you have the original fuse holder, check for loose clips - they're riveted together and the rivets can loosen and allow corrosion under the clip. The cure is to drill out the rivets and replace with small bolts/nuts/star washers. The best results come from replacing the fuseholder entirely with something newer.

Sometimes I have to spin the fuses in the clips to restore contact. Cleaning them with a brush awhile back was effective, but it seems the old metal likes to oxidize in the Tidewater climate. Be nice to put some kind of protectorant(must be one of my words) on them that doesn't make a mess or melt off when the coach gets to a hundred degrees inside.
