    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.

Actual charging system output in watts/amps???

This is what I measured using a current amp on a stator wire and scaling to total output for all three legs. Don't infer that because the stator current rises to over 20 amps when shorted that it will do that when applying the voltage to the load.

I figure max out is about 15 amps at 14.5 which yields 217.5 watts.

The 15 amps flows to the electrical system plus goes into charging the battery. Figuring C/10=14 Ah/10==> 1.4 amps charging current for a good battery.

Pos, to this uneducated mind does the chart on the right mean the Compufire RR keeps more power going to the bike's accessories?

No not really, I am looking at the maximum current that the Compufire will flow . Since it is Series that is all going to the electrical system so that is about the best estimate of total current coming from the R/R. Multiply that by the voltage delivered and you have total power delivered.

I also have direct measurements of the R/R output but this graph was more convenient.

We can gather from the Compufire design (not these charts), that there is more power delivered because it is more efficient (i.e. has lower voltage drops). That probably means in a side by side comparison it will push a little more current. I don't have those measurements to confirm that. I would not expect it to be a lot more.

Your 217.5 watts seems about what the article also claimed for the 1981 GS1100E.
