    I'm not electrical savy. I notice my Opus was having the same symptoms right now. PC haven't been up for over 2 days already, and I didn't had the time to trouble shoot.

    My question is how does the diode put in? I have no idea what series means. Is the diode one directional? which end is supposed to face the battery terminal. I assume it's the (+) terminal of the battery right?

    Can someone draw me a picture of how it's supposed to look like? Thanks.

    Does anyone have a part number for this diode? Exactly how large is a 10 or 15amp diode anyway?

    It's been cold here in MN last couple of days (4 F or -16 C). Carputer didn't turn on twice already :-( Is there some more information about this solution? Part number, pictures, how to?
    Thanks

    guys,

    let me share my personal experience with the 90W opus PSU. I experienced the "not booting during the cold" problem myself and what I discovered was that MY PSU simply doesn't function normally (fail to boot) during cold weather. It has nothing to do w/ excessive voltage drop during cranking in cold weather because I disconnected the power to the PSU overnight and in the morning, I started the car without the PSU being connected and then I go ahead and connect the power to the PSU and it still fails to boot (cold weather). What worked for me after that is that I unplug the power from the PSU again and then let the car warm up. After about 30min, I connected the power to the PSU again and it boots up and works just fine.

    So my conclusion is that I beleive the PSU is just not designed for industrial temp range. Or at least not all the units that they produced works for that range.....

    My Opus 90w has been working fine in the cold weather of the last few days (well, we didn't reach -16C but we did have -6C)... Also, my laptop HDD works fine and spins up without a glitch... Maybe it's because everything is mounted in a plastic box, so the (very little) heat produced by the standby power of the opus keeps everything from freezing?

    Wish I could help you guys!

    once again, let me stress that my experience has nothing to do w/ cold cranking. It has to do w/ the fact that OPUS 90W PSU is simply not designed for the cold temp. I suggest people who are having problem try the following:

    Disconnect PSU from the battery at night.
    In the morning (cold), start the car.
    Connect the PSU to the battery.

    If at this point you are not getting the flashing green light, that means it has nothing to do w/ the cold cranking.

    I'm in Minnesota, and am gathering the parts for my system. Last week it was -20F. If the Opus can't handle these temperatures, I don't want to buy one (obviously). Can anyone do more tests, or confirm or deny this? If someone sends me an Opus I can do some tests, but I'm definitely not buying something that will leave me hanging when its cold.

    I seem to have the same Problem vith my Opus 90W PSU.

    on Friday it worked Fine, now it won't start (since the Weekend we have about -2 til 0C (Germany))

    I havent tried it now (have it in my house since about 3 houres)
    Everyday it is Could, it doesnt work. Thats ****.
    I thought the Opus is a great PSU (starts at ignition, shuts down the PC automatic etc ...)
    But if thats the result (hardware thats leaving me alone ... ) I will kick it to hell and bye a normal 230V PSU and an Inverter.

    hope anyone will have a solution (IT's not an cranking battery or a Voltage drop down)

    I have been having the same problems with my Opus 90W. I did the below tests and contacted Opus, which was very helpful:

    -Test1: Had the car's charging system and battery tested. Was told they are both fine

    -Test2: Fully charged the battery with a home charger, with charger still attached removed the connector sending power to the Opus started the car. Opus failed to start the PC

    -Test3: With a 12V AC-DC converter. I removed the PC from the car and took it inside. While the PC was still cold using the converter sent power to the Opus. Opus failed to start the PC. It took about 15-20mins before the PC would start in the house using the Opus 90W.

    -Test4: Placed the PC outside for a couple of hours in the cold (about 9F) then attempted to start the PC with the AC-DC converter (which worked in the house). Opus failed to start the PC.

    With the results from these tests I contacted Opus and reviewed my findings with their tech guy. They told me there may be a problem with a component on my board and that I should return it. They promised to send me a replacement that has been fully tested. However since I have a long road trip ahead (10-12 hrs 1 way) I decided to pay to upgrade to the 150. I haven't seen any reports of the same problem with the 150 and didnt want to take the chance on another 90W.

    My recommendation to anyone experiencing problems with their Opus is to do some trouble-shooting. Once you have isolated the cause of your problem, assuming it is the PSU itself contact Opus they are very helpful and seem to have a genuine desire for their product to live up to expectations.

    Hope this helps.
