my alternator went out the other day. so I replaced the brushes, and still nothing! so I pulled it again, and now i'm lost. I got the alternator apart and I'm testing the diode assembley, between the diodes I'm getting resistance about 2.5 ohm's, the book says there should be infinite resistance between the diodes. so does that mean that where should be no numbers on my meter? this is out of a 00' tacoma 3.4L. what eles should I check well I have it apart?m
