    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Hi All
Getting ready to go on a 2 day junket, and am concerned a little about the charging sys.
Have a 80 550E ,replaced the R/R with one that has a sensor wire. The voltage at the Battery will not go above 13.4 V even at 5k RPM. Is this normal . On Bikecliffs' quick check page it indicates the Voltage should be about 14v, however if the R/R has a sensor wire and its from a different bike should I still get 14-15 at 5k.
Am I OK to go on my hop.:confused:

THANKS
 
Make sure you have a good ground between the reg and the battery. Check voltage between the battery + and the fuse block + reading should be less than .5 volts
 
I have one ground going directly to the battery and the other to the frame.
 
13.4 VDC is not a good charging voltage. Why did you replace the RR ? What was the charging voltage with the old RR ? Did you check the AC output on each of the three legs of the stator ? I would be leery of any trips too far from home.
 
I'm getting 60 v AC on all three legs of stater...The R/R was replaced because of poor output 12 v?
 
The charging volt seems to top out at 2500 . Have a spare SH543-12 but I don't see it listed under compatible R/R.
Thanks

I have a SH-541-12 unit- two green, two red/white,3 yellow and a black sense wire- is your unit similar? where did you connect sense wire on this other R/R ( the one that you are testing now) ?
 
Hi All
My apologies for not updating sooner... life got in the way and haven't been riding.
So ..In spite lower than normal voltage, I did go on my 2 day 600 mile ride and experienced no electrical problems.
Two weeks ago I finally had the time to dig into the system and I did find 2 problems.
First..
When I replaced the R/R I used a 4 flat male to female connector(used for trailers) with conductive grease on the pins and some of the existing connectors ...Bad move with the grease and original connectors .
Replaced all the connectors with good quality flat spade connectors with a dab of anti-oxidant grease.
Second..Checked all my soider splices and found 1 bad joint (loose) .
Now the system is happy and all the readings are textbook .
Thanks for all the help, without it, I wouldn't have found my stupid mistakes.
