Ok so having spent most of the day with the heater on, I also took the seat unit and fuel tank off (it's really difficult when it's your first time) to look into the wirings underneath and trying to find an earth to the frame that might be messing up.
Unable to find that, I did find the earth wire from the ECU to the battery and it looked a little corroded at the join, so I've cut that out and replaced it with a new join.
Meanwhile, on the battery side, using the multi meter I can get the following readings:
No ignition - 12v across the battery
Ignition and nothing else - 9v across the battery
Engine on - 13v across the battery
Now the "interesting" bit. If I have the ignition on, engine light goes out and I hit the electric start or the horn, the battery dies (goes down as low as 1v across the battery). However, leave it a few seconds (approx. 10-20) and it slowly 'recharges' back to 9v across the battery.
I'm no electrician, but I'm thinking this is an indication of something shorting out when the circuit is completed with either horn or push start?
Anyone got any expertise or experience to share on that one?+
Also, for additional head scratching, the original issue with the revving seems to have gone UNLESS I hit the electric start either prior to, or after firing up (I know, you shouldn't need to after it's fired up however, it seems to me that the problem itself still exists and it's better to get rid of it completely than allow it to 'only happen on xyz condition'). Then it will go back to faffing with the revs again.
