Voltage goes up and down,,depending on rpm.Connecters for regulator/rectifier get unusually hot.Battery voltage decreases the longer you run the bike.
SOURCE: wire connector between stator & voltage reg/rectifier burnt
your voltage/reg. can be tested in a couple different ways check ground res. check res. then revs. bias on diodes you have ac in dc out it sounds like you may have a diode gone bad allowing ac curent to flow causing the wires to get hot
SOURCE: All lights dim, when applying brakes
when the lights dim is the bike idleing or is it above 2000 rpm if its ideling its not producing enough power back to battery so it will dim the lights. rev it up a little and see what happeneds
SOURCE: my battery is not charging when bike is running (gsxr 600 k6 )
When you put a voltmeter across the battery terminals, you should get >13.5V (typically) with the engine running.
If less than this then your charging system is faulty and your battery will not charge.
See this personally authored thread for a diagnostic guide on how to determine whether you have a problem with your stator or Rectifier/Regulator - inlcuding some cold resistance checks you can do on the R/R to determine if it is shorted.

It was written initially for Triumphs, but applies to ANY 3-phase motorcycle charging system.
SOURCE: Can a voltage regulator/rectifier if not working
YES!
Good link here:

Symptoms:
Lights flickering at times and/or battery gets hot to the touch
Problem:
Reglator/Rectifier
When the regulator dies, it allows as much as 19 volts to appear across the battery. This is not good. It will cook the battery and the battery could even explode. Fuse can not stand up to this!

Hi bscruggs5, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
What are the voltages? What is the maximum, minimum? The connections will get hot under normal operation.
