GM Alternator Rebuild **Note to all TZE owners

[Matt Colie]

While the Hemmings tutorial is great, one best pay attention to the fact that the TZEs were all a type 27SI small frame.
They are very much like a 10SI, but one of the big differences is that ours have a large diode trio and there is no resistor because ours use the
remote sense lead for a voltage sense. Other than that, the pictures are real good.

FWIW......

According to the 78Z gmc parts book, the resistor was used in our alternators beginning in 1975. It's not pictured, but is listed as part of the PN
1101016 alternator introduced for 1975. This jibes with what I found in my 1975 Eleganza. OTOH, the resistor is NOT listed as part of the 140 amp
alternator which was an (apparently rare) option in 1978. Wiah I had one of those!
