The smoke regulator has gone out on my VisionLine CP ES44AC. Lionel does not have anymore available to repair this engine. The unit smokes but the fan motor is only getting .6 volts to it and will not turn. Has anyone been able to repair one of these boards or is this a sign of things to come with replacement parts for these expensive trains. If anyone know where I can get a 691SFC1102 SMOKE FAN CONTROL PCB / DIESEL HYBRID board please share.
