Default Re: DC motor speed control

Hello.

Before delving in too deep, try removing the 1/4 watt resistor from the choc block connectors. I agree with Merlin, the two presets are for minimum and maximum speed settings.

It could be that someone has ‘ modified ‘ the unit by fitting this extra resistor.

Good luck!!
