Still working on 12volt lights

[Whoachubby]

A few days ago I posted about the five decorator lights in my 99 discovery that have no power.

Three of the lights are wall mounted in living area and two are mounted at head of bed.
I got a wiring diagram from fleetwood and they appear to be on the same circuit as the other 12 volt lights. Everything works excet these lights.
I took a 12 volt tester and eliminated bad bulbs as there is no power to the fixtures. All of the fuses under the refrig. Look good.
Anyone have any ideas where to search next?

It still sounds like a blown 12 volt fuse. Have you checked for power at the first link of the chain?

You say the fuse is OK after removing and resetting in fuse holder, whats left is checking the wire terminations from each light to the other.
Startt at the last working light in your wiring diagram.
The wire nuts or crimp connection may have come loose and need to be changed or re-twisted or crimped.
Connections can come open from road vibration.
Make sure you check the ground side of wiring as the battery side connections.

Regardign the fuse... Did you meter across it with an ohmmeter (Should be zero, same as touching the probes to each other)

I've seen bad fuses that looked good.

Following that if the lights are in a slide out, or if the power wires runs via a slide out you may have a broken wire. Even if it's not via a slide you may have a broken wire. That can be a genuine PITA to trace without a cable tracker (Harbor Freight sells those)

I concur with the broken wire theory. 3 of the five lights are located on theslideout wall.
Have never heard of a cable tracker so will look for one tomorrow.
Also purchased new fuses .

I pulled the fixtures from the wall.

Getting plenty of power.
Bypassed the switches and lights work fine.
It seems strange that all five switches would be bad.

The Harbor Freight model is not for powered circuits. It could be used with your DC circuits, but you will need more electrical knowledge to do so.

If there is a disconnect in the wiring a tracker/tracer will not be able to find it, you need to open each fixture and hopefully there is a disconnect in the fixture wiring. If not the tracker/tracer might help you find the breakage point in the wall, not a good situation.

There are devices that can track live wires, but they can get expensive.
