To move forward, I think Brien needs to identify with certainty where to measure voltages on the LIN_REG_EN, V_IN, +12V, and VDD nodes

I have found it helpful to solder fine wires, color-coded, to the various nodes and bring them out where they are easy to access.? Makes voltage readings easy and less chance of an "oops!" slip shorting something out.? I tape them to the bench with the ends readily accessible for connection but spread out so they can't short to others.
I use this, it has 8 colors and works great: ?
