Excessive Ripple = definitely Bad Alternator?
A typical diode failure will show an asymetric wave. 300mV may be OK at the alternator''s output terminal but I would not expect it in a GOOD battery when measured at the terminals of the battery–not the battery cables. A sulfated or broken battery would invalidate the so-called ripple test.
AC ripple in a DC system
• Due to the discharge/charge effect the battery lifetime is limited • Due to ripple during charging the charge power is reduced. • Due to the ripple also other connected loads will suffer from the same ripple Tips: 1) The height of the ripple can be seen in VEConfigure 2) DC Ripple can also be measured by having the multi meter on

Alternator Ripple Testing: The Ghost in the Machine
A multimeter can read AC voltage and can be used to test for ripple. The alternator should be replaced if AC voltage of more than 50mV is detected (in some cars as much as 100mV is acceptable). A dead or weak battery can throw off a ripple test, however, so you must make sure the battery is fully charged.
