I know that; it's just that one wire had become disconnected! I thought that it was amazing that it ran as well as it did with one motor! A friend of mine, Larry Pearson and myself, have become real experts in working on these motors. We are able to re-build Lionel Pendulum type units that work flawlessly when we finish with them. Here are a few photos of the motors that were in a magnificent Mojave 408E boxed set that I acquired after I worked on them. The set would run beautifully on about 13 to 14 volts!!
And, the final result, the set in operation!
