battery at 12.3 is good , as long it maintain 12.3 v at igntion switch on

new altenator . good there

no i think you have a igntion switch problem or a loose ground ,

check

1- igntion switch power to starter

2- check the grounds on the switch and the stater

3- all fuses need checking inside & outside the car

If you check the voltage again at start up and it dims down inside , the interior light or dash display , i mean or the voltage on multimeter drops , then a bad starter should be suspected
