O Scale / HELP Christmas Emergency! Lionel KW failing after running for a couple minutes, is this something I can fix? See video.
« on: December 24, 2023, 10:34:38 am »
The kids and I set everything up only to learn our transformer has some sort of issue. Christmas eve and no chance of finding another.
Is this something I might be able to fix? I know enough to be dangerous but am capable of disassembly, soldering, light troubleshooting, etc.
This video should tell the whole story, but basically on a workbench with no load and a voltmeter hooked up it seems to operate fine. With the train when just plugged in it seems to work fine, but then after a minute or two it will stop, the voltage will drop, and the output will "stutter" on and off a bit, and basically just not work. Sometimes knocking it on the side will cause it to work again for a few moments.

I've taken it apart and nothing seems loose or wrong that I can see.
Only thing to add is that the other output does the same thing. All the fixed voltage outputs read as they should (although did not check under load). Does the same thing on two engines (a Williams and a 90's Lionel).
Help save Christmas!
