Drink selection dead

[VendMomma]

Newbie with a Seaga here (yes, I already know 😂). 

I have a drink selection that doesn't work. Totally dead. It started out sounding a bit "weak" then I thought I fixed it and it lasted a minute and now totally silent when testing motor. 

I have swapped out motors. Nothing.

Swapped out home switch motor. Nothing.

I hooked up a working selection to the connections of the one that is dead and it works. (D3 working connection hooked into motor of nonworking D4) However, it does a complete rotation. I am assuming it is the wire connected to the motor (the one with pins). Maybe it's something else? If it is that issue, how do I replace JUST THAT selection?

have you cleared all errors?  It may have jammed and taken itself out of service. Clear errors and I think it will come back to life.

I did clear the errors. I was hoping it was that too!

Try running a motor count.  I have had seaga boards that wanted to "lose" selections and it will usually re-find them on a motor count.   If it happens once it will reoccur though, so you will always have issues with that machine.  Sorry.
