Good day!

I'd venture to think it's a draw on the motor of some kind... A/C compressor kicking on, or even an electrical load making the Alt work harder... something very subtle but constant... I suspect a failing component would throw a code if it happened every minute or so...

Just my two cents...

Cheers!
