Good day all. Long time lurker and recent joinee because, like most that join here, I have a problem!

Its an 04 Rancher 400AT and the battery is not being charged. I was out riding with a fully charged battery when after a few hours of riding the 4wd light began to flash and eventually the quad stopped.

- the battery is about a year old
- The battery when fully charged reads 13V and slowly drains as I ride. The battery does not drain when the quad is off, only when the key is turned.
- I've left the battery sitting for over a week and the voltage didn't move.
- I've changed the voltage regulator, same issue.
Below is a reading I took of the stator. I've found lots of descriptions saying a reading of O.L is no good but I haven't found anything regarding straight zeros across the screen. I just want to make sure I'm going down the right path, or that I'm measuring it correclty before ordering a new stator.




Any help would be appreciated...I hate not riding!

its toast man. is there any continuity to ground?

I have not looked up the specifics on this unit, but have you downloaded the service manual to explore those details? If not, you will find it under the first link here, Honda ATV Schematics / Manual Help - Honda ATV Forum

Is that the test where you leave the lead in the stator and touch the chassis with the other? I did that and it was ok, it read open line.

alloutdoors, I have the manual and it states it should read between 0.1 and 1.0.

that is correct AnotherRyda. By your readings there is no resistance through your stator. When your multimeter reads 0 its the same as touching both leads (of your multimeter) together. You should always read some resistance. 0 ohms is essentially infinity and lets ya know something is messed up.

Thanks Johnny. Going to order the part. I will update the thread once it's installed.

Hi: Try this unplug the stator place you meter on the AC volt scale -- test yellow to yellow on the connector with the bike running --what is the AC reading???

It won’t start with the stator unplugged. Just keeps turning over. Pull start doesn’t work either.

Hi: Sorry about that -- unplug the regulator/rectifier and test for AC volt on the yellow to yellow there.

Same thing...just keeps turning over. Should I be starting it then unplugging them?

Hi: The one at the stator needs to be plugged in -- just unplug the Reg/Rec to test for ac volts.

Hi JohnnyLouder - not meaning to nitpick, but 0 ohms is not infinity. A reading of 0 ohms means the winding is shorted. An open winding (open circuit) would read very high resistance or OL, which is infinity.

Above post is true -- Quote by Joeyou --Zero ohms is not infinity

AC readings on the 3 yellows at the regulator were .076, .076, and .064

Hi: That is bad news with those reading -- you will need a new stator

Thanks. Part is on the way. Out of curiosity, what should they be reading?
