Having sadly broken down last week and been carefully taken home by 911 courtesy of my RAC policy I have since had a look around the bike for the problem.
As I was filtering through the traffic the bike gave one tiny stutter and I knew straight away there was a problem. No sooner had I felt that the bike cut out. Pushed bike to the side of the road and tried to restart only to find the battery only had the power to switch the starter solenoid and not the starter itself hence the RAC.
Removed Battery cover and metered found to be 12.6v dropping to 6.3v on ignition. Metered the Alternator phases and all three sat at 0.8 ohms ( Mr Haynes says between 0.4-0.6 ohms but say there test bike read 0.9 ohms on all 3 and was ok )
Next I went to the reg-rec and found this.
As you can see the yellow wire is burnt out and would bet it has damaged the reg-rec as well. By the green deposits on the wire it to me is a tell tale sign of water ingress. Next step- New reg-rec and try and source a new connector. If anyone knows where to get one please please let me know.
Thanks in advance Stuart.
