1990 Nissan 300ZX

I have a 1990 nissan 300zx. It has around 156000 miles on it. When I put the key in the ignition, all the acc. Lights come on. So I know there is power, but when I try to start the car it blows my battery fuse and in turn wont start or turn over. I have checked the starter and it said it is good. Do you think it could be the alternator or a bad ground.

Easy. Do a voltage drop test on ur starting sys.
Tell me which fuse it blew. We must have work on 100 300ZX last year. No big deal.
Good luck man
