Hello, why the motherboard, typically pressure problems are related to the compressor

Check the compressor.....

Mark83, if the pressure test fails I would put back the 74 motherboard, check the compressor, the two filters and the regulator. Most important take apart the regulator and give it a good clean, lots of slime and corrosion inside - typical symptom pressure rising too slowly, times out and fails. Hope it helps.
