Ok I'm tinkering with an SI-Deluxe kit I got untested from Wu. (I assumed it would need work no big deal).
Anyhow - thankfully before I plugged the board in I tested the power supply. Found -5v dead, +12 is really almost 12.2, and the +5v seems to bounce between 9 and 11volts.
That said, I then realized the +12v fuse on the power brick blew. Replaced it, and it blew again.
Here's the kicker/question - there's a bunch of diodes near the harness plug. For some reason, my meter is reading ALL of them except for 2 as OPEN. Does that make sense? The two in the corner which looked baked are reading shorted. Does that sound like my meter may be acting up? Its a nice Fluke so I doubt it, but damn I can't get ANY of the diodes to register ANYTHING either way, just seems wierd. Is it really possible this PS is epic fail, even though it sorta worked?
