Avalon VT 737 sp

For caps that can be just fine. Zero can be just fine too. They don’t test the same as other things. Here’s what to check:

On the compressor board, what is DC voltage of pin 10 of the J1 connector? (black probe on any ground)

What is DC voltage on the top of R3? (It should be the same)

16,3 p10
And 1,9 on r3

My bad, actually what is the dc voltage at the top or r4? I got confused by a dark shadow on a pic I was looking at,

Ok good! Then the top trace and the bottom trace appear to be connected. So that might not be the problem. I will have to wait til tomorrow to think about it some more.
