Additionally when testing the alternator, the frequency output is incorrect, if applicable and or the amperage is not measuring correctly. A potential cause of the above conditions is that there are 2 types of rectifier and 2 types of stators used that can not be interchanged with one another. The one has 3 windings but is neither WYE nor DELTA until connected to the rectifier. The other has 2 WYE windings on the same stator stack. Proper part separation and identification is 2911 critical! On the picture labelled as 2911, shown on the right, there are 2 bridges that join the stator windings together. If these are closely examined they are the center (N) of the WYE winding so in reality this would be 2 WYE stators wound onto one stator stack. When testing the phase balance on this type of stator the checks would be: A-B, B-C, C-A and then D-E, E- F, and F-D. If the stator being tested is this type it is for the 160A alternator and requires the 12 diode rectifier to function. When programming this into a D&V type tester be careful of the 3 versus 6 phases!
