I am trying to find a Genteq pin layout diagram showing where voltage is supplied to get the different speeds. I would, if possible, like to build a tester with dip switches to operate them. If someone has anything it would be greatly appreciated.
I think I might make a difference which series you are interested in.
http://www.genteqmotors.com/products/ will lead you to information on each series.
They also sell a tester for their motors.
If you check their installation manuals the wiring diagrams are included.
I don't know about any except for the Evergreem IM for sure.
This would be a good place to start, however.
