Not Holding Charge

[79XS11F]

The XS11 is know for it's weak charging system so it MUST be in tip top condition to work properly and not leave you stranded. How old is the battery? Could this be a coincidence and the battery is due for replacement?. I know for a fact that this bike will not run with a bad battery or weak charging system. The battery, in good condition is necessary to "close" the electrical system and have it work properly.

Brand spankin' new battery.

OK that's good :-) So run the required tests on the stator and while your at it run tests on the regulator.

Our rotors are basically a large spinning electro magnet.
Older systems used regular magnets, and for some reason, known only to physicists, you can knock the magnetism right out of them.

The battery is only used to start it right?

Nope... needs the battery to run. That's why your bike has been running. What hasn't been happening... is that your bike hasn't been recharging the battery.
The ignition system need about 10 volts to run. Under 10v, it may still crank over, but no sparky.
Luckily, my crash only ground a hole through the engine side cover. Your damage to the cover may have sent the stator coil into the spinning rotor, slicing up some of the windings.

Disconnecting the battery on a running machine can cause a voltage spike and burn out the regulator.

Anything else on the bike that would be killing my battery other than the stator not working right?

If your charging system is working properly, It should put out enough juice to compensate for any normal voltage drain. If you have a headlight wire(or other) grounding to the frame, you'd be blowing fuses, which you're not.
Nothing is killing your battery... it is being drained by all the normal electrical systems on the bike. It's just not being recharged.
Now yes, from a crash, I suppose internal battery damage can happen(plates get knocked loose, etc).
Need to see if the system is working.
Go to a cheap tool joint, like Harbor Freight, and buy the $4.99 digital volt meter. Hook it to the bike... battery should be around 12.6 or so. Start it up and rev it to around 2,000/3,000 RPM.
should show 13.5, or 14... anything other than 12.6. If the voltage doesn't go higher, you're not charging.

Nice one on Ebay... 8 hours left... Hurry! Well .. OK.. Nice and straight anyway! lol

Cover and Stator

Well crap.. that didn't work.. sorry. Ebay item 230154952772

[DenzComp]

Yup. All ready on my watched list. I all ready was looking at that one before I knew I needed the stator. I wanted it for the cover. I must've jinxed myself.

[DenzComp]

Just realized that after I got the jump I either left it on the ground...or put it on poorly...plastic side cover is MIA.

I drove back up and asked inside to see if anyone turned it in...no luck...not on the road on the way home either.

I was just so excited to have it running I was in a rush to get it back home...

I'd like to have another maroon one if there is one out there...if not any color would do.

Please PM me if you have one.

I will answer th question about swapping xs stator to xj1100. Yes it is possible to use the COMPLETE xs assembly. on the XJ1100. You have to use everything from the xs including the cover. andreas

It all comes down to the molecular structure of the magnetised object. Everything is made up of atoms,when an object is magnetised all of it's atoms are lined up with their positive and negitive polls all pointing in the same direction. In a non- magnetised object all the atoms are pointed in all directions.Thus when a magnetised object is struck a hard blow these atoms are scattered, pointing all directions. You can de-magnetise a screwdriver by laying it on an anvel and hitting it a hard blow with a hammer. A handy thing to know in an emergency. Just think yesterday I could'nt even spell fizzasist.

"Magnetic deviation... off on a tangent again!"

And all this time... I thought it was the "Polarized Magnetic Gremlins" living in the screwdriver wanting to jump to the huge mass of iron anvil.
Hey, while on the subject, I'll play your game...
Last year, after not running it for several years, my home generator stopped putting out juice. I was told that it had lost it's residual magnetic charge.
I took the "generator" section apart and fired the thing up. Using jumper wires from a 12v battery, I touched the ends to where the brushes connect to the rotor. I guess that's how you re-magnetize the field or something. Works fine now.
I just found that interesting.
Guess I need to fire it up once in a while(Yeah, I know, I should do that anyway)

[DenzComp]

I tested both the magnet and the stator. They both did not give me the numbers they should have according to the Clymer.

I guess everything inside there is ruined.

I'm going to be looking for a replacement. If anyone has a cover and the guts please PM me.

THanks.

[DenzComp]

I'm worried that maybe I'm testing it wrong. I don't think I am...

Do these two normally go bad together?

[skids]

It is highly unlikely to have the volt regulator, the stator, and/or the field coil fail at the same time! Mr. Spock, what is the probability? There is a connection behind the fuse panel that can really get corroded and sometimes melt the connector. One is from the VR to the stator (3 white and one yellow wire) and one is from the VR to the field coil (1 green and one red?).

I think it was green and brown. That's where I tested at. They were extremely clean.

Either way...I have a replacement of both parts on the way from Andreashweiss. I'll put it all back together and let everyone know how it goes.

[trbig]

andreashweiss,

I realize you can swap entire assemblies, but I was wondering if JUST the stators are interchangeable.
