Reply to "Seen this before? MTH LED Full Vista Dome 20-64071"

I will have to open it up and take pictures for us all to look it over and come up with an action plan. Thank you John for the link to the steps you previously took. I am hoping it will be an easy relocation for the capacitor. I will add the choke if MTH did not. I believe it is a 22uh 1/2 watt correct?

I don't have this version of car, but it sure looks like there's plenty of open-space on the lower level?  Keep this in mind if/when you open up the car and take photos.

That is, I think it goes without saying that a soldering iron will be hot and ready to effect a relocation.  Some MTH cars pass AC track voltage from the lower/chassis-level via spring-contacts to the upper/shell-level.  The AC-to-DC conversion is then done "upstairs" and hence the capacitor must reside upstairs since capacitors are DC devices.

But if the AC-to-DC conversion can be done downstairs where there's presumably more room, then the capacitor can be located downstairs and you can send DC over the spring-contacts between lower and upper level.  This is just idle speculation in the spirit of a forum discussion.  The idea is to take plenty of pictures as I'm sure there are many alternatives.

If for whatever reason the capacitor absolutely must reside on the ceiling...since the soldering iron is already on perhaps breaking up the capacitance into, say, 3 or 4 smaller capacitors in parallel would not be as visually obtrusive...
