I attempted to install a turbo 8088 motherboard in my 5155. The board powered up fine when hooked up externally, but I must have shorted something to ground when I mounted it in the system because the power supply fan did not start. So then I disconnected all the power leads (motherboard, disk drives, even the monitor) and flipped the switch on. Still nothing. So I then pulled out my multi-meter and found zero volts on all leads. I took the cover off and found the 3 amp fuse near the switch and removed it to test it (hoping for an easy fix) but found the fuse tested good. I can't see anything that looks burn't inside. When turned on it makes a single click that sounds like a small relay but no fan and no output. Can someone help? I'd be willing to ship it both ways if someone would be willing to look at it. Any sugestions?
