Hi Nik,
Welcome aboard, with regard to your probs... I am not sure how the wiring loom is set up on your bike (my SS is a 97 carb job) but I suspect it may be similar to the setup on my ST2. I have similar probs but mine included the engine cutting out from time to time.
On the left hand side near the headlight is a big multiplug seperate that and check for bad or dirty connections try wiggling it while the ignition is on to see if you get any response (before you pull it apart)
Any way thats my twopennorth....what do I know I am living with the natives
