Old Shimpo RingCone Popet Stuck Clockwise

[brettwulc]

Hey all - I’ve took on the task of helping a friend fix a couple old shimpos. I’ve read the other threads and manuals - tried the wheel spinning trick and nothing seems to be working. At this point i’m wondering about switching wires on the controller to get it counter clockwise. I’ll include a photo of the controller, mainly wondering if anyone knows which wires switched will do it. I figure it has to be this yellow green and red, just not sure which and don’t want to fry anything (to the left is the lamp) The controller contacts look really clean and no corrosion. 

The wheels were donated and she teaches at a school and wants them to be counter clockwise. I know in eastern countries it’s mostly clockwise and not much of a difference for learning but it’s just what she wants. Thanks for any help!

Green is ground so leave it alone

 

Shimpo is still in business so CALL THEM and ask them if this is possible before frying the controller

I would switch the motor wires over the controller wires but they will know if you can do either or nun of the above.

only if its a DC motor as noted below

You can find this out with a simple tester-ac or DC

Definitely not green as Mark said! Green is your chassis ground for safety. No point in livening up all the metal parts on the machine and making it a shock hazard. If the motor is an ac motor then not likely you will be able to simply switch any two wires. If it’s a dc motor then yes, likely. A definite call before switching anything though.
