    Default 1997 Cincinnati Arrow 1000 (A2100) - Communication Board

    Hi all,

    Has anyone ever encountered the LEDs and relays on the communication board flickering? When main power is turned on the LEDs over relays CR12,13,14,15&18 are dim and are flickering on and off. Seems like there is a short somewhere. I checked the 24VDC power supply, I'm getting good voltage there.

    I have tried starting the machine but it will not make it thru alignment. Getting a number of random errors.

    Any help is greatly appreciated.

    Thanks!
    Kyle

    You should look at the I/O card in the A2100 control, that is what turns on the relays. Also look at the AC ripple on the 24VDC supply by turning your meter to AC when connected to the DC supply, it should be under 1 VAC. Also look at all the connections and ribbon cables connected to the board and the A2100 I/O card.
