What fuse did I blow

[Uncle Dat]

I was removing my alternator and stupid me forgot to remove the battery first. I accidentally touched my wrench to something then bam, a spark. Now I put on a new alternator and crank my car. Everything is fine except all the electricals are dead. I mean all except my headlights. Windows, Audio, speedometer/tachometer aren't working, brake lights, and even my A/C and heater is gone. I tried to replaced one of the fuse FL75A but didn't do anything either. 1996 240sx

You blew the 100 amp battery main fuse.

Where is the 100amp fuse main fuse? Same fuse box in the engine bay?

It is the under hood fuse and relay box on the passenger side of the car.

No problem brother. I am pretty sure that fuse bolts in . One of the bolts is kind of a pain in the a** if i remember correctly .

IIRC it's a 75A alternator fuse and auto stores won't sell them. People on eBay sell them.

I beg to differ, my shop gets them from the local O'Reilly store all the time.

sx moneypit, you are the man. Thanks a lot for your help! It was the 100amp battery main fuse. I got it at Advance Autoparts.
