Hi Grant,
This Brach, the electrical designer here at ZDL.
I’m curious what voltage reading you are getting from your power transformer. What AC voltage do you get across the brown wires coming from the power transformer (not from ground, but across the wires)? What AC voltage do you get across the Red wires? What DC voltage do you get at testpont 1 (from ground)?…If you get nothing, are the bridge rectifiers (BR1, BR2) in the correct orientation?
Thanks.
