What is the purpose of the fan inside the boiler? At what voltage should the fan operate?
The purpose of the fan is to cool the motor. In most cases this is not needed. However if you load the locomotive in the sun for a long period of time the temperature inside the boiler can rise considerably. The fan keeps the motor cooler.
It is a 12 volt DC fan.
Hope that helps

Thanks Stan, is the fan on all the time? If so, what effect does it have on the smoke unit?
