Title: Amiga 2000 PSU problems
Post by: orange on December 15, 2003, 05:22:32 PM
My Amiga 2000 power supply doesn't work. At first it clicked and fan was trying to start. Then I took it to the repair man in service. He told me he can't fix it; and that now fan does work, but the voltages are "crazy", instead of 5v there is 12v, etc. What could be wrong?

When measuring the voltages, have you attached a load to atleast the +5V supply? To that power-supply it might be wise not to use the A2000 motherboard as a load, use two of those 21W 12V lightbulbs often used for the break-lights in a car, or some other appropriate load that wont be damaged. That will give you a load of about (21 + 21)/12 = 3.5A on the 5V line (assuming they are linear) which should be enough.

How do I connect those two light bulbs; in series or parallel?


After searching within past messages,I've seen that A LOT of people had problems with their Amiga 2000 power supplies. There must be some common problem. Anyone knows it?


BTW I can't belive there is winblows message icon  :-(
