Hello,
This is my first posting so please don't beat me up too badly. Q: 2002 K12LTE, where is the Generator located? I looked but I didn't find it in the OEM CD. I know it's behind the tupperware but where? My Battery light was flickering, now it stays on all the time. My battery is good so I thought I would check the brushes on the Generator. Will I have to remove anything else to gain access to the Generator? I'm thinking that the the brushes might be worn down. Easy repair but not easy to find. When I find the Alternator, and remove the brushes(on the regulator 2 screws) does anyone have a go to place that might be more cost effective than the BMW shop for a new regulator.

If you wouldn't mind sending a responce to my email too [email protected]

Thw alternator is located on the right rear of the engine sort of in front of the battery. I have never removed one on the LT but have read posts that it is not a simple job. Unless you have lots of miles on the bike I would suspect a bad connection before I would suspect bad brushes.

Hello irnbt

What is the running battery voltage ? should be 13.5 VDC - 14.00.
Brushes in alternators are not the ware part that they were in generators as they do not carry the charging current just the field current around 2 - 4 volts and almost no Amps .
Yes the alternator is in their , just west of the battery deep in the bowels you can see just a small piece of it .

If you have over 40,000 miles on it, the slip ring on the alternator could be worn badly. Mine was, and I have a used one I purchased as a spare which also has a badly worn slip ring. I intended to rebuild it, but totaled my LT before I got to it. For some reason (polarity causing one to wear much more than the other?) the front (inside) ring wears much faster than the rear one.

The slip ring assembly can be replaced by an alternator shop, it is the one for a Bosch Internal Fan application.

If your alternator shop does not know which one it is, you can get it here:

http://www.wagneralt.com/
Click on 'Product Lines'
Then click 'Product Catalogs'
Then 'Slip Rings'
It is slip ring assembly W160-02

From what I have seen, the brushes far outlast the slip ring!

The alternator is accessed by lowering the back side of the motor along with the transmission.

If you do not find any loose connections and feel you must replace/repair your alternator,
purchase a low mileage used one. They go for under $100.00.

My alternator went for 120k miles and I replaced it because I changed out the transmission. (along with the starter).

Good luck

Thank you everyone for your comments. I am deciding whether I want to tackle this sooner or later (Fall). I appreciate your help.

Thank you,

G'day, Beryl Beemer had a flickering battery light early on in her life (musta been 9 years ago now) went back to the dealer (Oz warranty was only 1 year then, so know it was between years 99-2000) chemanic siad he was able to get his arm down to where the generator was and fix a loose connection. That was say back then, probably 0-20,000kms........haven't had any repeat in over 10 years and now up to 186,000kms. Not sure exactly the connection that was "reconnected" but said he didn't have to pull any tupperware off......

cheers

ya best check your wires. It will be frustrating to do all the work and end up just tightening/replacing a wire to "fix" it.

Not knowing the history of the bike it's difficult to say over the board.

Perhaps someone in your area can give you an extra set of hands/eyes to address.
