That’s what I was thinking
What should it be?

All three the same or very similar?If so I think that is OK.

They’re all the same. Manual says 60 so not sure if 80 is too high?

I was mistaken when I posted my 70 VAC as mine is the 300w Stator on the Curvy.The,"S" versions I believe use a 275w Stator.

Is it possible some one has upgraded the Stator to a higher powered one?

as long as all three outputs are the same and MORE than 70VAC and less than 90VAC you have a healthy stator.

the more voltage the stator kicks out the more the regulator has to work so produces a little more heat.

contrary to popular belief its actually bad to run the bike without your lights on. you want to use as much power as you can without sacrificing charging/ignition system. once a battery is fully charged it should only need a trickle from the RR to keep it healthy.

Good to know thanks. Maybe I’ll fit some heated grips to use up some power

I think there's a few here mistaking voltage for current.
If the voltage drops then the current draw will be higher.

I.e.

55w @ 12V DC = 4.583 Amps
That's basically one headlamp bulb on a battery and engine off

55w @ 14.9V DC = 3.691 Amps
That's the same bulb but this time the battery is charging....the engine is running.

It's the current that overheats wiring and connectors, not voltage.
Now it could have been a corroded connector that's caused voltage drop and so the current draw has increased. However, I would be cautious as to why it melted in the first place, jump starting a motorcycle from a car is fine. Running or otherwise.

Please don't ever try jump starting a car from a motorcycle though!!!!!

So a faulty battery could cause a increase in current and melt wire/connector?
