If one of the voltages is outside the above parameters, or the voltages are considerably below the 24-27V range then the generator coils have failed and will have to be replaced.
If the voltages are all within the parameters above, then the reg/rec has failed and will have to be replaced.

Been having intermittant starting probs, as though battery was flat. On Tim's advice, cleaned the contact on the actual start switch and thought that had cured it, but it has not.
For starting problems, have a good look at the starter relay first. It's the rubbery, boxy thing attached to the +terminal on the battery, with a 30amp fuse on it and two heavy cables. Check the cable connections (they're on with good solid 10mm nuts if I remember right) and ensure that they're properly cleaned, greased, tightened and tidy. I have a starter relay spare here if you want to give it a try. I'll check it's right for your FI model before sending it off
Run a load test on the battery. Make sure the batt is fully charged. Connect the voltmeter across the batt terminals (voltage should be 12.6-12.9ish) and crank the engine on the start button for 10 or 15 seconds. The voltage will obviously drop under such a load for such a period, but it shouldn't dip under 9.5 volts. If it does the batt is weak.
I did the stator test, and all three readings across the yellow wires are 40 V, way above the 24-7 range. There is no resistance continuity between any of the yellows and earth though.
I've no books in front of me so don't know for sure, but 40V sounds like a lot more than I'd expect from the genny coils. I would suggest giving Jaws (or anyone who knows what the output of a healthy FI stator should be) a ring. It may not be a problem at all as long as the reg/rec can cope with that input constantly.
Doing the reg/rec test ( with the headlight on, as it says in the manual ) voltage climbs to 14.47 V DC up to 2000 revs, then falls away back to battery voltage of 12.83 V above those revs. Incidentally, voltage does continue to climb to 17 V without the headlight on.
With the lights on and the revs above say 2000 and above, the reg/rec should provide voltage that varies but in the 14's, to run the electrics and recharge back to the battery. The reg/rec does sound faulty to me, on the grounds that it shouldn't drop to 12's when the lights go on. I would also, as a matter of course, check earths around the bike as well. That kind of V dip sounds 'earthy' if nothing else
Would you suggest changing the stator? Thats an oil out job I suppose. ( Only recently changed it )
At the moment Chris, no. I'd certainly speak to John (or whoever) first to find out about the stator output, before coughing up for parts.
Regards,
Chris
T.Murphy wrote:Chris, re the stator. Just for info in the future it is not an oil out job. When you take the Alternator cover ( "genny" is such a twee word aint it) off you'll only lose a small amount of residual oil from the housing itself. ( with bike on centre stand of course). Nowt worth worrying about.

Try twisting the throttle a bit more - that will help heat dissipation

... you change your regrec quite often then...
