Re: Miss-wired Pulse . . now it's dead
1 Data

3 Gnd
Since that is what was on my circuit board, I thought I was smart enough to put them in the correct order when I created it, I did not.
If I short the tube clips, the voltage drops to near 0V as you anticipated.

Re: Miss-wired Pulse . . now it's dead
Previously, I had just shorted it before like the troubleshooting suggested looking for a click.
With my meter there is 3v between TP1 and Ground w/ or w/o the micro.

Miss-wired Pulse . . now it's dead
I mis-wired J6, and now everything appears to be dead.
-I still here the whine of the HV when it's turned on
-I'm not getting anything from TP1 to Ground.
What are the likely candidates for parts to replace/check?
