Hey, it's still a 6'er!

I know, I know. Sacrilege. Posting about a Honda CBX on a KZ1300 forum. 

I should be taken behind the barn and shot.Well, the old girl got a new top o da line Yuasa battery.
Maybe that will help the over charging issue?Nope.
 Not sure what's going on. 
But with stock alterntor, 14.6 all the time.
With Tim's CBX Zx7 conversion, 18+Put a new top o da line Yuasa battery in.

Volts low until a few miles in.. then the RR kicks in.
OEM unit.

I have to figure this out. 
After about 30 minutes running, the voltmeter 'wiggles' approx 5 or so volts.
I installed cheap digital voltmeter across the battery, it reads 14.6.
Too high, IMHO, for stock alterntor.

It was ain AirHead Day

Turned 14k miles!Blah Blah.

Took her by the healing church. No luck. Still overcharging.

Thought I'd help a brother out and do an internet search on CBX high charging circuit and stumbled across a topic with your name all over it back in 2021 

You've been there and done that

I know. Sadly it's still not figured out.  

Hey, I can't log onto cbx club site anymore.. can you? Or is the site no longer accepting log in? 

don't know about the login. I just did a search and it opened up the topic I linked. Reading the topic there was a lot of info about the connections corroded and how the reg/ rect reads the system voltage and adjusts the field energy to control. The fact that you experience reasonable charging and then a few minutes later, you have a fluctuating voltage, leads me to believe you have a bad connection and as it heats up, things start to happen.
1.5-2.0 volts above battery voltage is a reasonable charging voltage for a lead acid battery. If you can get the charging circuit to hold steady at 14.5-14.6 V  I would be happy.

(FWIW)
