 OK I need some help I got a pce duo I got off eBay pots where messed with and  cap job was semi done  I got system up and running now my cd drive won't spin I messed gently with the pots and got drive to spin  also read once for a bit and froze  I need proper pot readings  from a working unit  I got the list that tells u all the readings from all the legs but there not adding up  my question is what's the proper pin  to letter diagram what pins are A-B-and C  another way I set this type of pot is by  probing the ground wire near the cd drive to the top of the pot  where u a just it not the legs   it's the method used to ajust  same pots on a 3d printer servo driver it gives u a good reading can some one probe a good unit and give me the values thanks

Welcome to the forums, can't answer your question, but I just wanted to recommend this as your avatar.  It will go nicely with the name.

First, this is damn near unreadable without a single punctuation in the entire post.  Second, read the "REPAIR GUIDE - laser swap and adjustment" sticky in this thread.  Welcome to the forum.
