Alternator Question

[Steve Sears]

Vittorio,
If the alternator is one of those 110 amp units, then the two bolt pivot is 
correct.  If it is the 90 amp unit, then it should have a long bolt and nut 
at the pivot.  If you were to hook a long jumper cable directly between the 
snubber mount to the battery ground, would you get a different reading? 
(The engine ground to chassis across one of the engine mounts may be bad). 
You might also check the condition of the battery cable splice.
Cheers!
