    HELP, Wiring diagram for Extron/ Hafco BM 90VCNC mill needed.

    I recently bought a 1997 model mill, knowing that it had issues, but believing that they could be fixed.
    The automatic oiler does not operate on power up, or every 30 minutes as it is supposed to.
    And the Z axis servo does not show its position on the DRO, and once activated, does not stop until the off switch is operated. Encoder or wiring issue?
    I need a wiring diagram to start sorting these problems, but the local (Australian) dealer cannot help, and the manufacturer Extron (Taiwan) does not answer emails to their support site.
    Any help, particularly wiring diagrams, would be much appreciated.
