    mobo problems :(

    ugh, so i go out to the jeep today and nothing works.

    the opus isn't flashing but has power

    so i bring the computer in, hook it up to a normal power supply and now when you press the switch the light on the mobo turns on but nothing else happens

    it's a shuttle fv24

    any ideas?

    I also have an Opus and a FV24 board. It happened to me once about a month ago. I pull the Opus' main power wire fuse, drained the Opus caps, recharged the caps (to avoid sparks when inserting the fuse) and reinserted the fuse. Got in the my truck and fired right up.

    how did you drain the opus caps and recharge them?

    also, why would the mobo not work with a normal power supply tho any more, that i don't get

    to discharge cap slowly, use a 12V test light aligator clip goes to black wire, sharp end goes to the red wire and wait til the light goes out.
    to recharge the cap, ground the black wire first, the aligator clip goes to the 12V on the battery side, the sharp end goes to the red wire on the opus. In theory, the light will go out when the cap is fully charged. On opus, there's a constant drain so the light will never go out. Once you get a light going, connect the red wire to the battery. The easiest place to do this is at the fuse by the battery asuming that you powered the opus at the battery.
    The reason for charging and discharging the caps is avoid sparks which sometimes can scare the crap out of you and to avoid the thought of "did I just blow something up?"
    If you have a large cap like .5 farad and up, you should always discharge the cap when not in use and charge the cap before using.

    Have you checked the internal fuse on the opus? its a 15 amp fuse. If all else fails pull it out and send it back to Opus.
