Default irregular voltage regulator

i've done two multimeter battery tests on my new Optima 6v battery. with the engine NOT running, i get about 6.5v. that seems reasonable...but with it running (which i assume reflects the charging voltage coming through the voltage regulator) i get 10-11v. which seems excessive.

...wondering if the previous owner who had had an 8v battery installed, also tweaked the voltage regulator (American Bosch Inc. 6v Positive) to let 10-11v through in order to charge the 8v battery. although even an 8v shouldn't need THAT much voltage to charge.

that has been the extent of the re-charging system testing as of yet.

what say ye?
