Hi ! Im looking for a electric diagram of pcb assembly treadmill drive SERIAL:0004-03052. The name of the treadmill Quinton Clubtrack 510 plus . I have already found Service and User Manual for it but , there nothing specific in it. http://www.manualslib.com/products/Quinton-Clubtrack-510-Plus-3260889.html. I need this diagram , because I want to fix an error E211 , which is really annoying . The service manual says that it can be a problem with motor or with VSD and it must be replaced, but the motor works fine , so im thinking there is something wrong with VSD. But it is too expensive for me to buy the new one so im trying to find where is the main problem with it and fix it .
