Hi Nelly - Success!! I took off the rear sub loom and checked it over, all fine. Then checked each indicator, again all fine. But then I added the indicators to the loom and checked from the white connector from -ve through loom, through indicators and back on the +ve. This threw up a fault in one of the black original Ducati connectors. I removed both and replaced with individual spade end connectors and then they worked! Not quite sure how a faulty connector causes the symptoms I had on both indicators but it did. Thanks for pointing me back to basics to go over everything. Took bike for a spin this evening and they are still working
Great news... It's always good to start with the basics and not to get carried away with how complicated these bikes are. They're still joined up with wires and spade connectors
