Hi Guys,

We bought a used 2006 Innsbruck Supreme i30TBR last year and the lights in the bunk have not worked since we got it.
I was just checking it out this past weekend with a meter and I was getting 13.3vdc at the bulb but neither bulb would work.
I took out those bulbs and tried them in other fixtures and they worked fine.  So it's not the bulbs.

They get power from a 12v cigarette type adapter.  The previous owner must have forgot to unhook it when bringing in the slide
because it was taped up/repaired with electrical tape and connectors.  I did notice that the wire from the new connector compared
to the regular trailer wire was much smaller.  I thought maybe it was wired backwards so I tried the other way and the plugin thing
got really hot but still no light.  There was 2 large resistors inside the plug... that's what got hot.

I'm going to buy a new more heavy duty plugin thing and try that.
Are the 2 wires coming out of it polarity sensitive in this situation?
I think the bulbs work either way they are slid in.  They are 921 bulbs.
The light fixtures look like Camco 41330 on Amazon.

Any advice or suggestions would be greatly appreciated!

Thanks in advance!
