Interior light help on a Trillium 1300

Hi, we recently got our family Trillium. The "porch" light by the front door works but none of the interior fixtures. Was hoping it was just the bulbs but I don't think all 8 are dead. Would like some recs on troubleshooting the wiring, and reccs on LED fixtures to replace the originals. I want to keep everything pretty basic vintage style, but the majority of the square light covers seem to be missing anyway. Want to post some pics but having trouble figuring out how that works in the forum here. Thanks!

the square covers are readily available from rv supply places, is there a battery in the trailer, some 1300's didn't work unless there was a battery, if they were converted to LED, make sure the battery polarity is correct, Pictures of what you have would also be good, what style of converter do you have?

In the Trillium, all interior 12vdc lights (and the porch light) use the same circuit. Are you powering them with a battery, or the original converter, or a replacement converter?

In either case, because they all use the same circuit you need to use a multi meter/volt meter to check for 12vdc voltage at each fixture.

Regarding the interior light fixtures, the shade covers are still available on ebay and other sources and are relatively inexpensive. Regarding LED bulbs for these fixtures, you can purchase good quality bulbs that are relatively inexpensive. Make sure the bulbs are designed to operate at a wide range of voltages, i.e., 10-18 vdc or 10-30 vdc.

Here is one source for the light covers:

There is no battery presently, it was tested with an electrical cord at my sibling's house and with "shore power" hookup at a campground overnight. The inside outlet also worked, just not the lights.

We don't currently have a battery hooked up yet - have been testing it with "shore power" but maybe thats the problem?

The converter is the original solid state by Progressive Dynamics, has a blue stripe on it and a switch to the right that says BATT. at top, OFF to left center, and TRANS. at the bottom. To the right of that switch it says 12-VOLT and has a little blue box that says FUSE 10A and OUTPUT below that.



I guess it's not possible for us to upload pics here without them being posted online elsewhere?

You can upload pics from your computer drive.

The interior lights and porch light are powered from a single 12vdc circuit from the converter regardless of whether you are running shore power (TRANS) or battery (BATT). Since the porch light is getting 12vdc power, that single 12vdc circuit is getting power. Check voltage at the interior light fixtures. If there is no voltage there while powered on with shore power (TRANS), then there could be a disconnect in the wires back to the converter. Then trace back / check power where accessible back to the converter. In my Trillium, that single 12vdc circuit from the converter has wires crimped together branching out to all light fixtures, so one or more of the crimps may have failed in your Trillium.

This is interesting because typically all lights, whether we're talking interior or exterior, on the same 12 volt battery circuit. In a later post you mentioned you have no battery. So with no battery your inside lights should not work, however neither should the outside light. I could be wrong but it sounds like the exterior light is on the AC i.e. the shore power circuit. Your post is over a month old. Have you found the issue?

Since you know that the porch light works, take the bulb out of the porch light and try it on the other lights.

I have found that the wires in an old Trillium age badly. I have found corrosion that has creaped under the insulation over ˝". It may be prudent to compleatly re-wire the trailer.

There is a good wiring diagram here:
