Place the ohmmeter on the two slip rings on the alternator shaft (in which the brushes Make contact with). There needs to be almost no resistance. Place one lead on the slip ring and just one over the alternator shaft. There need to be infinite resistance.
Tapping lightly with a Very careful!!! hammer round the circumference in the alternator exactly where the two halves fulfill may help separate the halves When they are "sticky". Entrance BEARING REPLACEMENT
