Unless a battery is flat my alternator churns out an unimpressive 13.6 - 13.9 volts. I prefer around 14.4 (even 14.8 max)even though this means checking the electrolyte more often.
Has anyone ever tried modding the ark-like regulator's second coil to stop it limiting so early? - (Forty years ago I had all the kit for relay setting but unfortunately not now)
A little bit folded paper
A little bit folded paper positioned under the spring worked for me.
Bit crude, but it's effective and enough to increase the amount of force/voltage required to switch the contacts
