Just replaced my stator, which was roasted, and I'm only getting 11.8-12.2 when the bike is running, which means it's still not charging the bike. Is it possible that my R/R also needs to be replaced? Or did I buy a faulty stator?

Sidenote rant: Just spent 2 1/2 hours trying to swap out the stator, and when I finished, I took the bike for a test ride. Came back, and noticed one of the bolts was loose and leaking a bit of oil, so I go to tighten it, and the bolt broke. Now I have to open it up again to take out the broken bolt. FML

You need to test the stator, separately from the R/R, to know. Time to break out the service manual.

This might be useful! It's a flow chart. I think I'm having a charging problem too ((((((((

Anyone ever used one of these? Looks like its a ammeter with a special attachment for fuses, but could be just the tool for someone troubleshooting current drain.....

Just swapped out the old RR with a Mosfet type (Shindengen FH020AA) on my 999. The stock RR was buried in the battery box near the front header, and being the Shunt type, it was getting very hot and unstable. Made a simple aluminum holder and secured it on the horn bracket mounts. Now it's running cooler with consistency in charging voltage! Thanks for the great info referred in this thread

Nice. Just printed it out. Battery fully charged, service manual, multimeter and battery charger in backpack, on my way to the garage. Thanks Alan for the thread, mods for stickying and Collin for the flowchart. Wish me luck!

not sure here, but I think how many times you need to light your stoplight, turn signals, etc. has a contributing effect.

I was wondering if there is any truth to the rumor that connecting a meter in parallel from the negative terminal to the case ground, showing current above that required for whatever memory, clock functions, etc. the bike has could be a tip off to a short, if the stator tests come back negative.
Also, to point out, in older bikes, yeah, its me here, connectors and wires in the charging circuit with any corrosion, gudge, broken wires, etc. might impede the battery from receiving full voltage. just my 2 cents.

And excellent modification to make and well executed as well.

Its Triumph specific, but there's useful info to be had.

I don't know the guy who wrote it (lives in Pleasanton).
Those are both authored by me.
Please note that on the T'Rat thread, I have just added (today) a new reference on Series Regulators. For those bike models that are prone to high incidence of stator failures, a Series Regulator should definitely be a prime consideration.
There are two readily available on the market:
The Shindengen SH755 is same form factor as the MOSFET FH012/020 Regulators - although the SH775 is SCR is a hugely different animal from OEM SCR SHUNT Regulators, so don't be put off by fact is not MOSFET.
This device is used as OEM equipment on Polaris ATV/Utility vehicles. Cost new can be had for under $70
The Compufire 55402 is purely after-market device (primarily aimed at Harley market) - this device is well-proven in the field in several applications where there is known to be high incidence of stator fails.

Bottom line is that the stator reliability will be greatly improved by utilizing a Series vs Shunt Regulator.

The very simplest test for a failed stator is to check resistance (isolation actually) between any one (doesn't matter which - all will measure the same, either good or bad) of the three stator terminals to engine ground: there should be isolation i.e. infinite resistance or open circuit - NOT Short
If you measure short (or any resistance really) then stator is burned.
Invariably most stators will read short when they burn as the winding insulation is fried and they will short to the core.
A short is 100% certainty stator is bad.
Isolation is not a guarantee of 'good' however excellent odds that it is.
To confirm (only if passes the isolation test) start bike with stator disconnected from R/R - measure AC Volts between the three possible combinations of pins i.e. 1-2, 2-3, 3-1 (does not matter which you call 1, 2 & 3) - all three should be the same at any given constant engine rpm (easiest to do at idle since the speed will be constant) If one reading is noticably lower than the other two, that phase is suspect.
Again, normally if it passes the isolation test it will also pass the voltage test.
If fails the isolation, don't even bother doing the voltage test.

Good Luck!

this one seems odd to me. 03 gsxr 600.

my bike struggles to start. everything appears fine, i just have to push the button REALLY hard, and then it starts right up.

i just had my charging system changed, and the bike was fine, about a week later this started.

That would be unrelated to charging system - sounds like your starter switch contacts are possibly burned or corroded.

It's not often we see such well articulated posts about electrical problems; I think this earns you a 'BARF diagnostician' crown.

The crown isn't protective head gear so be careful riding with it.

Thanks Ironbutt - appreciated.

A piece of equipment I would definitely recommend is some type of voltage monitoring device.
My personal preference and endorsement goes to the Sparkbright LED monitor
http://www.sparkbright.co.uk/products.html



It is inexpensive, tiny / relatively unobtrusive but gives you all the information you need for reassurance your generating system is functioning as it should.
My personal choice is the 5mm size - it's really small, ideal for bike use without having a big 'beacon' on your dash.
(the main product page says 8 or 10, but the 5mm is also available when you go to the buy info page)

He now has a new product he calls the Eclipse which is auto-dimming - reduced intensity for lower ambient light conditions so it is bright enough for daytime, but automatically reduces to avoid overwhelming glare at night. Nice feature & is automatic!

I have no affiliation with Sparkbright, just a happy customer. I have them on both my street bikes.
