problem in speed master the 8 motors that move the color cylinder in the 4-color dont work!

My dear friends What is the reason for the problem that the 8 motors that move the color cylinder in the 4-color speed master 74 It doesn't work... Attached is a picture of the motor

 

8 motors ??

 

Please describ more your issue yo know excatly what happends.

 

Yeah, if there's 8 motors and none function, it's something with the power supply or the power circuit.
One motor that drives the whole train, I would replace this single motor. Nothing lasts forever, it's probably just burnt out.

 

Perhaps it is 4 motors .. For every color or head of a motor, but everyone does not work, although I ask for an increase and decrease from cbc, the motors remain fixed, electrical nutrition is intact at the electronic circuits responsible for the motors ..(mot... mwe)

 

Is this a new machine? or an existing machine in where all motors stopped simultaneously?

 

Please i did not understand the question very well , which motor do you mean and please send me the machine plate to know which machine is it , and describ very well your issue then we can solve it
