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...

    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.

Remove the fuses to test? 81 GS850

Thanks to everyone's previous posts and expert answers and The Stator Papers, I've come to the conclusion that my regulator/rectifier is inop and I've ordered one from the folks recommended in The Stator Papers.

But I have a question about one of the tests in my Clymer manual. The first test is to measure battery voltage @ 5k rpm, after "remove the 2 center fuses." Now my 81 GS850G has 5 fuses, making it tough to remove the "center two" since there is one in the center of five. Also, the center fuse is either the Ignition of Main fuse, removing it (or both) renders the entire system dead and not startable.

So what gives? What did the writers intend here, since there is no "2 center fuses"?

I did complete the no-load alternator output test and have plenty of voltage across each connection per the manual, so my understanding is that connections, grounds and a r/r are in order.

the 79 model has only 4 fuses
two outer ones are "main" and "ignition"
they stay in for the test
the other two you take out

maybe this helps?
 
Helps to have all the wires hooked up!

Helps to have all the wires hooked up!

Well I ordered a new R/R and am waiting for it to arrive but tonight I think I found the problem. I left the ground wire for the R/R off the wire panel when I put everything back together earlier in the winter.

Hooked it up and now have 13+ volts at idle and 12.5+ volts revved up, which seems a little backwards but its always over 12 so I think I'm ok.
 
its normal for the voltage to drop when revs are increased
