RE: [CAD_CAM_EDM_DRO] bleed resistor

Thanks to you too Jon. It's times like these and people like you that make
me wish that I'd learned more in school.

~Well, the 80 V is the most important thing. So, you can put a 5 K Ohm
~resistor across it, and it will draw 16 mA. You can put an LED in
~series with
~
~this and have a caps still charged indicator. The time constant
~(RC) = 49.5 seconds, so the caps will drain to 36% of 80 V in 49.5 seconds.
~That will be 28 V. That will be safe to touch, but not safe to
~accidentally
~short
~out. When the LED is out, it will be safe to short it out, too.
