C19 Fan

[Jim A.]

What is the purpose of the fan inside the boiler? At what voltage should the fan operate?

[StanAmes]

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?
