EXCESSIVE RIPPLE
Figure 8.12
Figure 8.14
One or more diodes in the alternator aren't
functioning or there's stator damage, which is
shown by an excessive amount of AC ripple
current supplied to the battery. (Figure 8.15)
Make sure the alternator mounting is
sturdy and that the belts are in good
shape and functioning properly.
If the mounting and belts are good, check
the alternator.
