The larger alternator only has more *capacity* than the old one. The excess
capacity is not *FORCED* into your electrical system. The voltage it puts out
is the same. Since it has an internal voltage regulator, you do not need to
worry about the regulation circuitry either. Obviously, there will be more
current *available* should a short circuit occur in your wiring, but the
difference in damage from 45 amperes vice 35 amperes in a short circuit would be
hard to detect... 35 amps will do very nasty things to shorted wires and the
wiring harness. The wires might actually smolder longer before burning through
with 35 amps, while 45 amps would burn them through quicker.
