Good evening, All I am feeling stupid and I admit it. I just torn down, cleaned and reassembled/refitted my 1986 SEi's air compressor and valve bank. When I started everything ran and clicked as I thought it should. It just did not put air in the shocks. A very little for a while that then tapered to nothing. I found some oil where I don't think there should be any and I found a bit of something in the vent solenoid valve. I think it found the issues. I cleaned, greased and reassembled. Now there is NO power to anything. No lights on the pressure display. No action on any valves. No compressor. Nothing. I went over the connectors knowing that I just missed reassembly of one. Nothing. I feel dumb and know that I have missed something I took apart but I can't find it. And my manual's trouble shooting section starts all trouble shooting assuming there is power to the system. Okay, stop laughing at me. Tell me the obvious that I have missed. Then go back to laughing... And maybe part of it or another problem - no lights on the ECM. Yet it starts and runs just fine.
