Hi guys, >> >>I occasionally spend a few minutes when available trying to get my alternator >>problem figured out. Brought my alternator to Autozone last month and it >>tested >>bad, so I turned it in and got a new one. Thought I compared the old and new >>one together, but apparently did not do a good enough job checking it. >>Replacing an alternator should be an easy job, right? New one doesn't >>fit. I'm >>having a helluva time and my car can't be moved as a result. I wish I could >>get >>my old alternator back, just long enough to move the car into the garage. >> >>My questions: >> >>1. Do I have an alternator or a generator? My dash light says "GEN" and my >>'73 >>GMC Sprint manual calls it a "Delcotron Generator Assembly." The Autozone >>computer calls it an "alternator." >>2. Shouldn't there be a difference between alternators on pre-'75 and >>post-'75 >>models? I bought shiny new chrome alternator brackets thinking that the old >>brackets looked like something thrown together by some shadetree mechanic. >>The >>new brackets are good for models up through 1975. The Autozone computer >>shows >>the same alternator for a '73 307, '73 350, and a '77 350. Maybe they tried >>to >>make one alternator interchangeable with too many others. >>3. Where can I find some sort of identifying code on my engine? Given that >>the >>previous owner used this Sprint as a parts car for other cars, I'm not even >>sure >>I have the original 350 anymore. >>4. Am I an idiot for even taking this project on? >> >>Thanks all for your help. Nothing urgent here, but I sure would like to at >>least be able to move my Sprint without selling it as a parts car. >> >>Saul >>'73 GMC Sprint
