Thanks D man for the feed back. I had problems with 3- gen 1 suctions covers over the years,end up changing to gen-2 covers. Really like the gen-2 covers easyer to change suction temp/pressure transducer. Thank's again.
Have had issues with the IGV assemblies where the set screw has come out from the stepper motor causing it to spin in the housing and pinching the wires to the housing. Wires shorted and took out the mini inboard fuses on the backplane. Had to replace the backplane board. Have you ohmed out the stepper motor windings on the pins on top of the IGV assembly?
