Radio Noise
If you are getting radio noise that seems to be alternator-related, you can
use your multimeter to do a quick check of the alternator output voltage.
Set your meter to AC voltage and measure from the main bus to ground while
the engine is running. If you see more than one volt in the AC scale,
suspect a blown diode inside the alternator or possibly bad brushes.
Remember, the alternator is only supposed to output DC voltage. This isn
=99t
a perfect test, but it is quick and easy. A ripple meter is an even better
way to check stator and diode condition, but most amateur builders will not
have one in their toolbox.
