So, as I try to restore the Quadra, I thought that I'd start with the power supply. Searching the forums, I didn't find anything related to the pin configuration for the 9 pin socket that goes to the motherboard. I took a volt meter to it and this is what I found:
Positive lead (Black) to Negative lead (Blue): Voltage seems to oscillate between 3-4 volts.
Positive lead (Yellow) to Negative lead (Black): Voltage seems to oscillate between 7-8 volts.
Positive lead (Red) to Negative lead (Black): Voltage reads in at 4.2 volts
Any idea what that means? Assuming that Black is ground, it seems noisy at least.
I looked for a way to open the PSU, but I can't seem to find anything that isn't taking a screwdriver and prying the sheet metal apart. If there is a useful trick, I'd love to hear it.
Thanks for any advice you can offer.
