hey i was wondering what size alternator come on a 1996 4wd blazer.And what size inline fuse is there because i want to put a anl fuse on it when im doing my wire upgrade

 

I think it is a 100Amp

 

It depends on the RPO codes listed in your glove box as there was a higher amperage alternator offered, IIRC. The standard alternator was 108Amp. As far as the inline fuse goes are you talking about the one under the battery or the fusible link between the battery and the starter. The fuse under the battery on the radiator core support is a 100Amp fuse as Zasder stated.

 

My 96 4wd Blazer has a 100A.
