Greetings; Hoping to get some troubleshooting help here...I
installed a couple new modules today (and rearranged a bunch of old
ones), and at the end of the exercise my A100 won't come on....

The fuse looks ok, and i think juice is reaching the PSU (that big
block on the switch lead end of the PSU gets hot when I power up)...

But no power appears to be reaching the bus boards -- no modules, no
power bus LEDs, no nothing. Is there anything that can be done at
home, fairly simply, to test whether the PSU is still operating
correctly I've got an AC/DC voltage meter, but i'm not absolutely
sure what to test....

Regards
Glenn
