OK people, RESULT! with the help of my beloved we got it all sorted today. I swapped out the loom for the spare I had, it appeared that someone had meddled with the loom that was on it. Also swapped out the LH handlebar switch assembly as the connections on that were messed with. With the new loom the engine cranked on the button, but no spark. Searched around with a multi meter for a while and found the ignition pick up was not connected properly, cleaned that up and voila, all good. We fitted the stock clocks and got them working, then removed them, figured out what wires went where and then wired in the new clocks. The new clocks have an LED turn signal, which stopped the issue with all the indicators flashing at once. All I need to do now is solder all the connections to the new clocks properly and heat shrink wrap them. I used as much of the cabling from the stock clocks so I retained the big multi plug so they are easy to remove in the future.
