Electrical charging problem

So, intermittent problem has begun where the generator still works in both start / charge mode but intermittently no current is getting through to the battery. This gives "MAster Caution: Gen" and shortly afterwards the "Master Caution: Electronics". On/Off toggle GEN and ELEC RESET are not effective, though land and shut-down, it might come back fine.

I understand that the control of voltage flow to / from the battery is governed by the box behind the fuse panel in the cargo hold. This has 5 boards.

1. Anyone else had this problem?
2. Which of the boards / relays shoudl we investigate?
3. Does Eurocopter swap or fix individual boards?

Any other thoughts / ideas also welcome. We have checked all the wires and connections. Battery cap recently checked and is fine.

Thanks
