That’s a good idea -
I was going to suggest searching for a circuit diagram, but I doubt that exists for something simple…

It’s just a really really low quality shunt voltage dropper, if South London makerspace can’t figure out what value of resistor to put in we should simply give up doing electronics
Hi Joe
I tested V across the motor terminals (the motor works ) with a range of R values as below. Seems like you were spot on with 180R. I don’t think I need to make any adjustment for lack of load, but if that’s not correct let me know.
I now need to order a single 180 ohm resistor
Thanks again for your help… SLMS can indeed fix a low quality shunt voltage dropper!
The gadget is a “water pick” which pumps water through a nozzle for cleaning braces (of my cousin’s 14 year old) and I tested it without any water
All good as long as nothing is getting too hot
It’ll be the on load voltages that make a difference
