So I'm in the home stretch for finishing my MB-6582 but while soldering cables to the control surface and mainboard, I noticed that my continuity tester would produce a small click when testing the +5 and GND pins (the small 2-pin cable to the far right). Looking at the numbers of the multimeter, I'm getting anywhere between .400 and .800. Is that normal? It seems to be reproducible when I test the +5 and GND on the IC sockets as well, although not all of them show the same numbers.

I'm thinking this might be the reason I get lower voltage on the +5V in proportion to the load, but that was just a wild guess. Anyone with more experience mind qualifying my possible stupidity? :)

The short click is normal - that's the time it takes to charge the capacitors. To be on the safe side, check the voltages again w/o any ICs in it - if they're not ok, turn off the box immediately.
