I have set up a small postwar track in a storefront for a local shop using what should be a simple Fastrack oval and a postwar engine. Yesterday the owner called me and told me the train was just sitting on the track without power. I went over to the shop and sure enough it was powerless
I checked the outputs in the transformer and it was putting out ~10 volts but there was nothing on the tracks at all. I checked the wires and other connections but nothing. Suddenly when I touched the single section of track where I had the power connected it sprang back to life. I dismantled and I wiped the pins clean and it seemed to work again. All can think is some of the GooGone I wiped the tracks down with somehow got into the pins enough to prevent a good contact.
I am going to go get some denatured alcohol today to clean the track, but an wondering of I got some contact grease to put on the pins if it would help
