i have a xb12r that is not charging...
i do not have a shop manual, so i don't know how to check my stator and rectifier to see witch one ( if any ) is defective
any help on how to check these components would be welcome, or insight as to what the problem might be. Is there a fuse for this? i did not see one in the fuse box on the right of the handlebar..


thanks
Marc

just out of curious, why are you not taking it in under warranty? Hard to imagine an XB12 being out of the 2 year warranty yet...

my manual is not handy at the moment so I couldn't tell you the testing methods off the top of my head, in my case when the stator went bad, you could smell it from the burnt Mobil 1.

it is under warranty... but it's 3 weeks until they can check it, if the problem is not to costly i would rather fix it myself and ride for three weeks.

the oil does not smell burnt... so maybe it's just a wire, if you get your shop manual please let me know about what i should have at the different wires out of the stator and the regulator.

thanks

You won't get far without the manual, I don't blame you for working on it yourself (even if it is under warranty) just for expediency sake, but do take the time to get the manual.

On the Tubers, you would follow the wire from the stator to the voltage regulator, and disconnect it. While the bike is running, you would want to see like 50V AC on it. While the bike is not running, with the voltage regulator disconnected, you would want to see some fraction of an ohm between the pins, and infinity between each pin and ground.

The XB's have a three phase stator, so I would think a similar situation would apply... while the bike is running you should see 20 or so volts AC between any two pins. With the bike off and voltage regulator disconnected, you should see some fraction of an ohm between any two of the pins, and infinity between any of the pins and ground.

This is all pure speculation though. The manual would tell you for sure.

You aren't making an appointment to bring the bike in, this is a warranty work issue and if they are telling you three weeks to have it looked at, then call BCS and have them step it up for you. This isn't add on, or simple maintenance work, this is a faulty part on a time limited issue. The shop is suppossed to address these types of issues right away.

Listen well....
I told my dealership that I thought my stator was going bad when my bike was hard to start. Couldn't get it in for 3 weeks. During the week before I was suppose to take it in, I had to stop riding the bike. For the day of my service, the bike completely shut down on my way to the dealership and I had to get a tow. Dealership called and said the stator is on back order. Been out of a bike for 2 weeks now, next week will be three.

You should get approx 10V AC per 1000rpm out of any two of the three wires coming from the stator with it unplugged and motor running. If you get that then plug it in and start the motor you should have 14V DC at the battery. The power to charge the batt passes through a batt fuse in the fuse box, but if that fuse was blown you would not have anything happening on your bike when you turn the key on.
