    Last time I called them, they told me they don't sell power supplys for the HR24s or any D* model. They'll fix it for an unholy price, but they have to be going the same route I do to get the working power supplys.

    Calm down, Pete. He reported the same symptoms I saw on three 24-500s recently and replacing the PS board fixed each one of them.

    But I just reread the thread and have another question for the TS. I'll ask him in another post.

    Do the front panel lights come on when you plug in the 24-200?

    I'm calm ... But I feel something doesn't smell right in your description. How that bad PSUs could turn on a fan (+12V rail), light up LEDs (+5V and +3.3V rails ?) ?
    Major question would be the same - did you measure all rails on bad PSUes ?

    So far, on three 24-500s, I've heard the HDD spinning and the fan, very briefly, spin and stop. I can see no other way the HDD can get power except from the power supply board. I never said that you see the front panel lit and have a bad PS. If you don't have front panel illumination, it seems to be caused by a bad PS board. A board with more than one output. So, the HDD spins and the fan tries to and the front panel isn't lit up at all. Bad PS.

    And no...I didn't measure any voltage and I have no idea what a "rail" is. I keep saying I'm extremely lazy and replacing the PS board and having the HR work properly again is enough for me. It's quick and easy and you need no technical ability other than how to use a Torx wrench and pull connectors apart. Literally a ten minute job once you get the cover off. That's taking your time.

    Measure the voltage of a rail.... :lol:

    That would take a minute and you'll know if it PSU or mainboard. You'll not guess but have a knowledge. :lol:

    BTW, nice good DMM for such home projects is $5-$10. Only.

    I dunno, I was given it after my original Fluke exploded because it wasn't properly protected. After the explosion, we had people from Fluke (or whoever makes them) attend the Incident Review and they vowed to make changes to the new Flukes. All our old Flukes were gathered and we got the new Flukes a week or so later. Our law dept. was all over them.

    Same thing happened with Bobcats many years later. They used to be wide open in front and a contractor had a three quarter horse electric motor fall out of the scoop and injure his leg. We quickly welded heavy screening on the Bobcats we had on site and I do believe that Bobcat offers the protective screen doors as an option now. Didn't then.

    Just checked it, it's a Model 25. I've had it since ~ 1980. Thing's about half as big as a Simpson analog MM. The one that exploded was as long, but very thin and could be carried in my pocket. It was great for tight spaces.

    I will re-assemble it, plug it up, and report back.

    Thanks all

    And measure voltages (rails) - then post here too.

    Still works well...much like its owner.... :lol:

    I hated lugging that thing around on my tool belt. Still, it works well.

    Good to hear that. Hope next time you'll measure voltages (rails) on any PSU what will comes to your hands: working or not and will post results to teach some "cowboys" to proper method of diagnostic of such devices ;).

    If someone is going to the trouble of measuring voltage coming out of a power supply trying to figure out if its bad. They might as well go ahead and do component level repair instead of searching ebay for a used one. Much cheaper and might actually learn something doing it that way, if they don't make it explode instead.

    It's an engineering term for voltage lines.

    Rich, you know how on pc power supplies there is usually a +5v, +12v, sometimes a +3.3v, etc....outputs, those are referred to as rails. Sometimes when a psu goes bad only one of the rails goes bad, say the +12v....
