On the VSU-100, TP1 should be +5vdc, TP2 should be ground, TP3 should be -10vdc.
What do you measure on the non-working one?
Quoted from zooman:Spy: tp1 read .16 I thought tp2 was another loop and got 5.4 vdc and had my ground on the head ground strap and tp 3 was -9.4. Should I use tp2 as the ground and recheck tp 1 and 3?
Yes, try it with TP2 as ground and recheck TP1 and TP3.
I am not sure why it would measure different though. If the board isn't getting a good connection to GND maybe that's part of the problem.
