alternator circuit voltage drop and ripple voltage values

What would ba an acceptable voltage drop on the alternator circuit ?
Some say 0.2v, others 0.5v... i'm getting 0.5v on the positive circuit
and 0v on the ground circuit.

Also, what is the best way to test for AC in your DC (ripple voltage) ?
According to my DMM i'm getting 30v when normal value
should be under 0.09v (negative lead of DMM on alternator chassis
and positive lead of DMM on positive of alternator, DMM selector in the
AC section)

Thoughts ?
