Do all your 12vdc lights work OK when on shore power, but just not when on coach (house) batteries? If some DC lights don’t work on either shore or coach batteries (with use/store on), check the fuses in your DC fuse panel that feed the lights. Make sure all the fuses are tightly pushed into their slots and are not blown (failed open). Sometimes fuses can work loose with enough rough road. Also check for a loose wire connection at the fuse panel that is feeding the failed lights. A loose wire nut that multiples lights together may also be the problem. Finding the place where the connection has failed will be a challenge. You also could try checking at the light fixture (that does not work) closest to the fuse panel for a bad connection from the fuse panel. If the working lights are weak you might also want to check your coach batteries for state of charge and test that they are charging properly when on shore power.
