Battery voltage reads higher than Charging voltage

(1/5) > >>

rcb78:
I just noticed today that my battery voltage is reading higher than the charging voltage, see pic below.  I replaced my battery and regulator over the summer and when I did, I wired the regulator output directly to the battery instead of re-using the original connection.  Is it possible that the charging voltage is now reading low because it's after the battery, headlights, etc,, where before it would have been before these in the circuit?  Thanks in advance.

I guess anything is possible. Why not put the wiring back to the way it was designed and see what happens?

rcb78:
I did and no change.  Then I went back through a few logs I made before I replaced the battery and R/R and it shows exactly the same thing.  Additionally, someone on the ADV Rider forum posted on image of one of their data logs and show's the exact same thing I'm seeing.  So now I'm wondering exactly where the GS-911 is getting data for the charging system and if it's accurate.  I'm going to pull the ZFE sometime over the Holidays and double check all the connections and grounds to rule out bad contacts.

Alexm1:
Have you checked it with a meter? I have never used the gs911 to check charging, I just put my meter on it, battery can sit static at up to 12.3v, with charge 13.5 - 14v. Easy way to check. Good luck.

rcb78:
I have, voltage at the battery read with a meter matches GS-911 values.  Voltage at the accessory port (DIN plug) matches the lower value reported as the charging voltage.  Since that port is controlled by the ZFE, that leads me to believe there is more to investigate.
