I'm after a definitive answer as to the correct alternator model number for my 1980 - is it a 10SI or a 12SI?
I know the correct part number is 1101075, and it's a 70 amp unit. As for the actual design number, I'm getting confused because several people have said several different things;
I have been told the following:
It's definitely NOT a 10SI, and should be a 12SI.
The 12SI began life in 1983, and is recognised by a plastic cooling fan, suggesting 12SI is wrong.
The 12SI began life in around 1977.
Clearly, none of these statements agree with the rest...
Would there be anyone out there kind enough to run thru the major differences between these two styles, and also tell me what I SHOULD have on the 1980?
If someone could put me in the direction of some good literature on the subject, I'm happy do my own reading! Would this be the kind of info to come from the Technical and Judging Guide? (Planning to buy this soon)
Thanks
