I don't remember which line that is though and right now I'm at work so not a lot of time to dig it up.
    That's just it, I DO get a solid green light. But the board never turns on (except for USB stuff). If I switch polarity on the green and white turn on wires, I get the 2 flashes you speak of.

    Unfortunately, and embarrassingly, I never learned how to use a multimeter. Network Admin, but can't use a multimeter.

    I'm sending it back to the MP3car.com store for an exchange.

    with ANY hobby (or job for that matter) that has wires... you should invest and learn to use a multimeter. They're not that expensive for your basic functionality and not hard to use. And depending on the situation...could save your life

    Hope you have better luck with the replacement. I like my Opus, hasn't given me any problems yet (other than the goofy polarity issue with the power-switch lead).

    your battery voltage is probably too low for the opus to start...it is designed to keep you from running your battery down.

    Start your car, then check if it runs...

    In addition...you need heavy wires running from your battery to the OPUS...you will probably need a fused 8 guage wire running directly from your battery to the + of the OPUS...and a very good ground wire.

    Thanks for the comment. I actually have 8 guage wires running from the + and - of the battery. The + is fused, I had it installed by a car audio company.

    Right now I have the PC running off of an Inverter while I wait for MP3Car.com to switch the power supply out. I'll let you all know how it works out when I get the replacement. I can't wait either. I'm really tired of going to my trunk to turn this inverter on and off...

    Wanted to give everyone a follow up. I sent the 1st power supply back to MP3.com store. They sent me a replacement and it took all of 15 min to reconnect it.

    When I 1st turned the car on, I was so disappointed as my PC didn't start right up. And then, 10 seconds later, it worked!

    It's sooooo nice not to have to open my trunk to turn on and off a power inverter. I'm very pleased. Thank you MP3car.com forum and store.
