Hi, Richard.
Sorry, had a minute to check everything only yesterday.
If I understood correctly, I had just to connect brown wire with black one which goes to solenoid. Is this correct?
Didn't help. Same situation. Green led on red wire is not active, 100% flow simulation is not working.
I didn't notice any visible damages/burnt parts inside FCM - everything looks good. Probably solenoid itself is broken?
What else to check?
