I have tried wiggling the wires behind the battery,it seems to stop temporarily then plays up again,have cleaned all the connections,tested voltage when running ok at 13.8-14v,then drops to 12-12.5 when rev counter stops working,any ideas on the fault?
Thanks
I only started getting into the electrical side of things recently so you might be better waiting for someone more experienced but I think the highlighted part of what you said is the important clue to your problem and you need to be 100% certain that what you said there is correct because if the bike is dropping down to battery voltage while it's running it means it must be losing the ability to generate it's own electricity supply so if I was you I'd be checking the stator and the regulator/rectifier. For the stator check for continuity between the three phases, check the phase resistances, check if any of the phases are shorting to ground and check the AC output when the bike is running also check it's wiring and connectors going up to the regular/rectifier. If the AC voltage is in spec then the regulator/rectifier is probably the culprit. Sometimes electrical problems only show up when things get hot which might explain why you're only having the problem sometimes so do your measurements when the bike's hot and cold.
Have a look at these videos if you're not sure about how to do the stator tests. They sound complicated but they're easy to do and you don't have to fully understand them, just have to do them

Have a look at page 8-26 of the workshop manual too. http://foc-u.co.uk/index.php?action=down...iew;down=8
