I had a guide bookmarked that actually had a troubleshooting process for a sys 3-6 power board. It told me to unplug all the connectors except the input at 3J1 and 3J2, and then told me what pins of all the outgoing connectors had what voltages - 5v, 12v, 28v, 110v etc. I lost the bookmark somehow and now can't find the site. Anyone have any ideas?
