I have a sea wolf that I was told worked a few years ago. I disconnected main PCB wiring to test PS PCB. All voltages checked out great. Checked to make sure all motherboard connectors were clean, plugged everything back in and powered on. All I got was a lot of missile/explosion sounds, no video. Checked voltages, all were good, expect for the +5vdc, it was now at 1.5vdc. Tried to adjust on the PS PCB with no luck. I thought the PS may have problems, so I installed a switching PS for the +5,-5,and 12v(I had planned on doing this anyway). After powering on , same thing. All voltages check out, except for +5 it is now +2.5vdc. If I unplug the mother/daughter boards, All voltages check out fine. Anybody have an idea where to look next??
Thanks for any help
