As some of you know I have to sell my train collection so I'm starting to get the engines ready. I put my Lionel 221 on the tracks, it went a few feet sparked and stopped. It looks like the headlight wire is bare and touched metal. Anyway, I have to take the shell off, this looks complicated with all of the small linkage on it. I can't see that well anymore and any suggestions would be appreciated.
Thanks again,
Bum
