Late start, more thought on electrical layout and options. Then started looking at the cabin side FADEC harness.
Got everything wired up to a 12V supply with switches etc. but the supply wouldn't hold. The Serial Bus Controller (SBC) which provide the GRT EIS system with engine data wasn't working and the PC software couldn't see anything.
After some more investigation and testing I found the SBC B power / ground were incorrectly labeled by AeroSance - not a good thing! I re-validated all the power lines for the SBC harness and got a data stream coming out ok. The next problem seems to be the ECUs are requesting the fuel pump to come as there is low pressure (ie. no fuel) - the next step seems to be they reboot.... Questions sent to AeroSance.
