Just checked with multimeter at battery, completely cold state is 12.06v and dash read 11.3vI’d check it with a multimeter for absolute clarity before making too many assumptions.
Bit yes, depending on the construction of the battery, you’d typically expect a half charged battery to present somewhere near 12.2 -12.4 volts (again, this is just from memory.
Might even pay to have a pro look at it and test it thoroughly. No load voltage is only one indicator of health.
The battery actually plays a role here, regardless of the alternator.
I‘d be getting it looked at if for no other reason than to exclude it as a possible cause. Could save you some headaches.
