need some advice. I was running the the flyerchief northern yesterday. Running and smoking ok but after a while the loco came to an abrupt stop. Remote flashing the red led and unable to make the loco move. I found that I turn the smoke off with the switch the loco will run ok just no smoke. Removed the shell and unplugged the smoke motor applied some voltage from a battery and the motor did not run. I could see the fan not spinning. Am I correct that the fault of the fan motor stopped or shut down the loco? I will order a new smoke from lionel hopefully the loco will smoke again.
