Alternator Charging Help...

those numbers dont sound right.the large wire on the alternator and the battery positive should be at the same potential and the field wires should not be the same.try this for starters to check a couple things.start the car and put the test meter on voltage. put the negative test lead on the battery negative and the positive test lead on the alternator case.this checks for bad conections.you should have very little voltage. maybe a couple tenths. now do the same test frome the battery positive to the alternator large post.thats the one im suspicious about because you had different voltage readings.if you show anything let me know what it is
