IGH issue not yet solved. Three possible scenarios explored.
Cryocleaning steps shows the original IDR is not in a stable state.
Scenario 1: Using the original IDR unit with caution and workaround steps. This will be clear by end of this week.
Scenario 2: Using Goldman's lab IDR to control solenoid valves. The stepper valves, V6 and V12a needs to be replaced with manually controllable switches. G1 and G2 gauge needs to be calibrated.
Note: Goldman's lab IDR is not responding to power after few retries. Possible fuse replaced but still didnt work.
Scenario 3: If Scenario 2 donot work for any reason, we will use brute force manual switches to change solenoid valve states and use the stepper valves just as in Scenario 2. I am currently mapping the solenoid valve wiring. Original IDR can be kept in test mode to use G1/G2 gauge calibrations.
I will be removing V6 stepper motor today.

Shall we go with the consultation before removing the wire plugs completely?
