W2,W3 are for hall's that need a pull up. Check your hall sensors, many \nwill want closer to 470 ohm. The 1k is a generic value.\nhttp://www.cherrycorp.com/english/sensors/pdf/connection.pdf\n\nThe resistors across pins 9,10 and 15,16 are not typically installed, they \nare only used on really hot VR signals, to dampen the signal.\n\n
