We have a GE 6B dual fuel CT with MARKV controls that on start up our P2 pressure is hunting to extremes. Varies from 80 psi to 200, with continual hunting of the valve.
We have calibrated (checked the 3 P2 transmitters), replaced the filter on the SRV, changed the servo and checked polarity. What I would like is some input on which points I should trend on a start up to pinpoint our issue.
