GVRI/O PCB Service
The GVRI/O PCB relays all signals between the system computer and the controls. Each
connector on the GVRI/O PCB is keyed to fit only to the correct harness connector. Refer to the
picture below to locate the connectors and fuses on the PCB. The two 5 Amp fuses are for the
coin meter power wire only. See Figure 34 on page 49 for detailed wiring information.
Caution:
Disconnect the cabinet from AC power before changing the fuses or making any
connections to the PCB.
Important:
The USB port on the GVRI/O PCB must be connected to either a motherboard USB
port, or a specific port on the PCI USB card in the system computer, as shown on the label above
these ports (see Figure 38 on page 53 for more information).
Start Button Service
The Start buttons for each player are illuminated with 12-volt lamps. Refer to Figure 24 and
perform the following steps to replace the buttons, lamps, and micro switches:
1.
Disconnect the cabinet from AC power.
2.
Open the coin door and reach up under the control panel to access the buttons.
3.
To remove a micro switch, gently rock it to the side and remove it from the housing. Remove
the wires and install them on the same connectors on the new micro switch.
4.
To remove the lamp housing, gently rock the white plastic housing from side to side to pop it out
of the button housing.
