What should the voltage charge be?

EDIT: Sorry, this should go to the pre-2012 wee forum. Can it be moved by a mod?

Are there specs for the voltage charge while the engine's idling and for when it's revv'ing, say at 5K?

Not sure if I have a battery, R/R or stator issue...... Mine's at 12.4 idling and 12.8 revv'ed. Seems low.

thx.

If your voltmeter is reading correctly, that is low. 12.6-12.8V is maintaining, above that is charging, above 14.8-15V is overcharging. The spec'd output is at 5000rpm. Other rpms are likely to have lower output but you won't see it as regulator is limiting the output. You could have a low output, malfunctioning regulator/rectifier, poor connection between output and meter or malfunctioning meter.

14.2v seems to ring a bell. I'd try another meter before starting to change things.

To add to Greywolfs post...where you connect your volt meter makes a LOT of difference. Connecting directly to the battery terminals is always good. When working on my chargings system I found over a 1 1/2 volt drop when tapping into wiring in the fairing panel!

Should be a bigger swing between idle and rev'ed up I would think. Confirm your voltages again and let us know.

I'd say there should be next to no difference in the voltage measured at the battery between idle and max rpm IF the voltage regulator etc is working correctly.

What's the battery voltage, ignition off, engine at idle, at 3000rpm & 5000rpm?

That's only if the output at idle is near the high voltage cutout.

Thank you, GW and all the other folk, for the excellent advice.

The connectors were dirty, preventing good current flow. My shop did a full diagnostic of the wiring, the Regulator/Recifier and the stator, everything is good now. 1.5 hours of labor -- not bad considering they had to remove the tank, etc.

At idle, it's now 13.8 and goes higher at higher RPMs.

btw; I'm sure you think I'm a pud for not doing my own work ... but I lack the time and knowledge, at least for now.

Not at all! Electrical problems will stump the most experienced owners from time to time. Even professional mechanics cringe at electrical issues, they are not always easy to diagnose. Glad yours seems to be ok.

I was surprised to already see a little corrosion and discoloring on my negative battery terminal clamp. My bike is rarely ridden in the rain and stays in a nice dry garage. I gave it a shot of WD-40 and greased it up well with some petroleum jelly (Vaseline) and will keep a closer eye on them in the future.

Oh well, once again the charging system is not happy.

I rode it a bunch last night, always keeping the RPMs at 5K or above. But today I'm having the same symptons of the starter barely turning over. Luckily it did start.

Voltage at the battery with engine on is now only 11.4v and goes up to 12.4v revv'ed up. Bummer.

My mechanic said he's going to have to look at the regulator/rectifier again. This can fail intermittently, he says, whereas the stator tends to fail completely.

I'm really bummed because I had a killer ride planned for tomorrow that's now nixed.
