can someone tell me why there is a electrical contact on the front truck axel , I have disconnected the contact and the engine runs fine I noticed the wire that connects to the wiper on the axel that running thru the chassis had insulation rubbed off and was shorting out. The engine runs better without the connection I noticed when running true fast track switches it runs much better no sparks?
it would be nice if Lionel produced schematics on these engines I hate to start taking it apart after the first few weeks of ownership.
