ok i finally got to wiring up my car to get rid of all the fusible links but instead of using a fuse box from later dodge i used a pdc and then wired it to a fuse block but now when i turn the key everything is good but one it starts it blows the first fuse which is the 12 guage alt wire could the fuse im using be too small i am using a 40 amp maxi fuse medium size
