Low voltage readings on (PSU 2).

should be: = is: +12V = 4.3V -12V = 8.6V +24V = 7.6V

Anysuggestions? (Other than buying a new card.) Thanks, jsk

You might have something dragging down your power supply, I have had the color monitor do this when it approachs the end of its life span, I have also had the power supply itself go bad but the voltage is usually 0. Unplug the monitors and see what happens.

Voltage checks out ok after i unplug the monitor and unplug the dc voltage suppy to the y1 enclosure. I lose the 24v and 5v line completely when i plug these in and voltage drops on the +12v and -12v, which leads me to believe a bad power suppy. What kind of test can i do to the power supply for current output?

I do not think it's your power supply, its probably the monitor, I spent two days nearly four years ago on this problem, the 265's power supply can be dropped out by a problem with any of the voltages, they are not isolated. Try using a known good computer monitor instead of the systems monitor.

UP AND RUNNING!!! Power supply is good but i found two loose wires in connector 12PL26 (DC to Y1). I think i may have another bad connection inside the Y1 enclosure. Monitor seems to be working OK.

Thanks for your help, jsk

Check the surge protector on top of the power supply. Pretty common problem on the 265s.
