Re: power supply cap

Also, one might want to use a light of some kind, 24v or LED in
addition to the resistor.

I't always neat to have verification of power.

BUT, normal cautions apply, The absense of a light or the presence
of no light does not mean there is not lethal power extant in the
circuit.

(I think I got that right, no light means you might still die if you
touch the wrong things)
