[Elecraft] Whoops!

[Don Wilhelm]

If you are using a Rigrunner with fuses for your DC power distribution,
check the fuse.  I recently was temporarily 'mind-boggled' by a similar
condition - measured full power supply voltage with no load, but as soon as
I connected a load, the voltage dropped to almost nothing.
Those LEDs across the fuse that are supposed to tell you that a fuse is
blown will conduct voltage with no current load (just like a diode) -
Unfortunately, the dim LED did not overpower my workbench lighting enough
for me to notice it (they only light when a load is applied).
