My thoughts exactly, see if I can overdrive the alternator just a bit. I'll do up the math here in a bit.
@ _____ RPM x ______ diameter pulley = ____ Volts
I'll check both the idle & cruise RPM's, and then figure out the circumference of the crank pulley & the alternator pully and figure out how many RPMS increase will result if I shrink the size by _____ x amount.
