I think you may need a new smoke fan motor. I run the fan at a low speed by dropping the power to the fan when stopped. However, to make sure the fan starts, I give it a brief "kick" of full power to get it spinning, then it gets the lowered power. If the motor is going bad, sometimes they won't run on the lowered power.

If it's not the fan motor, it could be a bad FET on the Super-Chuffer, I actually had one of those recently, it was caught in testing. If the fan motor will run on 1.5VDC and doesn't consume more than 40ma, you may have a bad FET, it's the only thing I can think of. Of course, you could have two bad smoke motors.

Measuring the voltage out of the Super-Chuffer is problematic, it's a PWM voltage, not a plain DC voltage.
