Long story short, ZZR600, got a bad misfire then bike cut when clutch pulled in. Wouldn't turn over, battery was dead. New battery in today, got her started, voltage at 4k revs is only 12.4V so im assuming the charging system isn't working. I pulled the plug in the photo of the regulator and if you see the top left is cooked, will this be my problem or would this not be enough to stop it charging?

Also what would have caused this and how do I replace it, 1 wire cut or get a whole new plug. Should i look at the other end of this near the alternator for the plug down there? Its a bollix to get at and is covered in the dry oil so i haven't managed to get it off yet.

cheers

Quite common on honda. Google vfr regulator rectifier fault.
Depends on how bad the charging system is.
Stator, battery and reg rec.

Yea for sure. Fingers crossed it's just the connector. Maybe able to remove the female connector and replace. Otherwise replace reg rec.
Chances are its bucked your battery too

Sorted, checked stator and rr using multimeter with youtube tutorial. Cut the connector off and put spade connectors on, hope they last
