Actually, the voltage regulator regulates the charging of the battery by the 
alternator. It is supposed to keep the battery charged but not overcharged. 
It is normal to have a bit of voltage loss when comparing battery voltage to 
the voltage after it has run through a bunch of wire to an accessory. I 
think about 13.8 v. is normal for when the battery is charging.
