main fuse blowing '76 cb750

riettic
Was having charging issues and narrowed it down to the rotor.  Replace rotor, replaced r/r with new (the og reg was bad).

Now main fuse blows immediately upon ignition switch to power up.  I believe it may be a faulty r/r.  Is this possible?  Any ideas on how to troubleshoot?

thanks,
C

Hook up a test light in place of the fuse. Then start disconnecting wires until the light goes out. When the light goes out you have found your short.
