I have 2 of these animals in my workshop, and am running out of ideas.
I have had both the controller and BICU of BOTH tested by our electronics workshop, and 3 of the 4 boards came back as tested fine (1x controller is unrepairable).
What gets me is that the SC672 does still come up on strart-up, before the engine starts. I have looked over the point-to-point diagram to check that all the connectors are in the right places, but cannot fault anything there either.
This does not make sense!
Only other culprit I can think of is the PSU that is not supplying a line of power to the controller?? Any more ideas anyone?
