    I am still stumped on the 90 gsr....maybe i'm not knowledgeable about JDM motors...but I thought 1st GSR was 1993 (1.7VTEC OBD1) Do you mean a DOHC ZC VTEC?

    they don't make one...I'm pretty sure. You might have an LS dizzy when you tried and your b16 may be shot? Are you saying the original was a b16? Sorry just trying to help

    Sorry....only advise I had was the b16 alternator....if you still have the b16 one....go have it checked out (any stupid part store can check it and there's got to be a shop close to you that can rebuild it)

    any OBD0 alternator will work on this setup. as long as it has the round plug, it will work. on the issue of popping a fuse, you have a short in your engine harness. or in the alt plug itself. as for the low charging, check ground and positive connections everywhere.
