My 455 Oil Derrick stopped bubbling. Bummer !
I bought my 455 Oil Derrick in November 2016 at a train show in Salt Lake City. Installed it on my layout and she worked just fine. I had it wired up to 18 volt DC using a slot car transformer. Recently the Oil stopped Bubbling. The Pump Jack still works as it should. The bulb was still working, but no bubbles. The bulb I had in there was a 24 volt bulb and it was bubbling. Today I swapped out the bulb for a 18 volt bulb, still no bubbles. I wired it up to a Lionel Transformer set at 18 volts AC. Still, nothing.
Any Ideas ? Here is a video of the Oil Derrick working as it should.
