Answers: I own a shop, and looking within my books I don't find this information, but the easy style to get this information is; The amperage of your alternator is stamped on it somewhere. If not; later look it up at a parts store, and the replacement parts will have this information. The alternator is no smaller number than a 100 amp, and the fusible link should be 30 amp. A Blazer beside a lot of trimmings will require a higher amp alternator than one in need many things on it. If you can't find the stamp on your weak one, then the parts store have this information, and if you look at the replacements the application calls for, after you can't go wrong.
Glad to support out, Good Luck!
105 amp alt. Probably a 30amp fusible link
