When the battery voltage on my Sniper display reads 12.3 - 12.5 volts and flashes yellow, does this mean that the alternator isn't charging the battery?

Usual charging voltage for 12V is like 13.6 to 14.4
Mine does that at an idle. I’ve tried a new regulator new alternator always same result. I believe it is just the amount of amp draw at idle. No need to worry

Thats kind of what I thought. I don't recall ever seeing it that high, but looks to me like Sniper is trying to tell me something that I better pay attention to.

This isn't idle. Probably 1500-1700 rpm. We were on the street returning home from dinner when my wife pointed it out to me.

Voltage Regulator (ext.) / How it works
A lot of you don't like electric stuff and especially not complicated things like an external Voltage Regulator. So maybe it's time to explain how this black box with 3 or 6 wires works. It's really pretty simple. A VR (Voltage Regulator) regulates the charging process of the alternator. Our...

The above link takes you to and older post that is really will written. Describes how your ‘external’ voltage regulator works.
I think what you described above is normal. I run a Dakota Digital in an otherwise stock 1968 and has a volt meter vs. ammeter. And yes, sometimes it’s up around 14 volts, and sometimes at 12 volts….depending on the battery state of charge.
