Dead A2000 power supply

[KatManDEW]

I found an old A2000, with what appears to be a dead power supply. I opened it up and checked the switch, which was OK, but there's a fuse holder with no fuse in it. Should there be a fuse in there?

Thanks for the help. I'm gonna put a fuse in and check 'er out.

I removed the battery from this A2000. It wasn't in bad shape.

A fuse seems to have fixed the power supply, but the A2000 appears to be dead. The drive lights come on and stay on, and there's no display.

I found the A2000 power supply pin out online. My supply measures as follows (spec - my measurement)

+5 - +5.18
+12 - +11.83
-12 - -12.12
+5 USER - +5.17
-5 - -10.65

My +12 volts is a little low, at 11.83 volts. Abd my -5 volts is way off.... COuld that be a problem?

I found my power supply pin out on that site that tells how to convert a AT/ATX unit.

I did not test mt power supply under load. I'll try that.

Thanks for the information.
