Well this problem has now been resolved. This is the appallingly amateurish fitting by Morgan of the aircon relays that led to the burning out (twice) of the dash electronics board

The relays are now correctly mounted in relay holders up along side the other relays behind the dash. Impossible to get to and impossible to photograph but at least out of harms way. In the process it was discovered one of the relays was also faulty.
Morgan has been requested to cover it under warranty but in the mean time I had to pay for the work. I will get a refund if it is approved.
I really am not impressed with the fact that all these wires are left uncovered and somewhat vulnerable up above the passenger footwell. A simple sheet of black plastic would make it so much neater.
