The battery acts like a big capacitor. It will stabilize the voltage in the
system which is especially critical when loads are switching on and off. The
voltage spikes can cause collateral damage. But running an alternator not
connected to anything won't harm the alternator. Perhaps if run for a long
enough period the rotor could overheat if driven to max excitation (17 volts)
but a
quick check should cause no worries.
