I am getting 7 blinks. Unplugged the SU + SD boards (no shorts noted at the buffers of SU/SD) and connected the jumper @ SC50? and still got 7 blinks. Figured the SC board is bad. Removed the SC board and upon checking for shorts, I am getting the constant beep at all of the marked components.

I first test each component at pins 1 and 3 (out of the three pins), then I test it from ground to pin 1,2,3.

When. I use the "Danger H.V."...

Went and tested my SC board (SC20 2pin beeps) and found that the multimeter will beep on all of the ones that I've marked with silver, when probing pins 1+3 on the component.

When ground is the High Voltage plate: D641, 642, 643 beeps as well

With the normal ground, everything else that is marked beeps.

That's 16 components that beep when tested, am I doing this right?...
