Hello, I have a 1995 Nissan 200sx. I recently had a friend put a new alternator in my car and my 75A fuse blew. This controlled my parts in my car such as windows, fan motor, dashboard lights ect. So I went to my local Nissan store and picked up the fuse I needed. Everything is working, except my Tachometer (rpm meter I call it). It worked before I got the alternator, but not now. Any Suggestion?
