Coin Mechanism

Switch off power to the VGM. Unlock the coin door and swing it open. To clean or replace a coin mechanism, unlatch and remove it. After reinstallation, ensure that the mechanism seats fully its bracket. Close and lock the release latch, and then close the door. Turn on the VGM and change the mechanism setup. Test known good and bad coins to verify operation.

Coin Meter

Switch off power to the VGM. Unlock the cash door and swing it open. The coin meter mounts to a metal plate at the bottom the cash vault. Record the meter count before testing or replacement. Remove the plate’s four mounting screws, and then remove the plate.

Disconnect the meter wiring harness at the connectors. Remove front screws and slide the meter out. Assure that a protective diode connects across the replacement meter’s terminals. The diode prevents driver circuit damage.

Hard Disk Drive

Switch off power to the VGM. Unlock and remove the rear cabinet door. Remove the perforated metal cover over the VGM electronics. Disconnect the DC power cable from the hard disk drive. Unplug the ribbon cable from the hard drive. Don’t disconnect the cables from the CPU Board. Loosen the drive mounting screws and lift the drive out of its mounting bracket. Remove the screws. Save them for reuse in future hard drive installations. When returning a hard drive to your distributor, pack it in an anti-static bag. Box the drive in approved shipping container 08-8068.

NOTICE: Hard disk drives are very fragile! Handle them with care. Do not stack or drop hard disk drives. Keep disk drives away from magnets, heat and vibration.

Joysticks

Switch off power to the VGM. Open the player control panel. Mark and disconnect the wiring harness from a joystick. To separate the joystick from the player panel, first remove the joystick shaft. An E- ring secures the shaft. Disengage this E-ring with a small, flatblade screwdriver. Grasp the joystick knob. Extract the stick from the assembly. Then remove 8-32 KEPS1nuts from the corners of the joystick base. Retain fasteners for reassembly.
