So my battery terminals on my 1995 Legacy L Wagon corroded to a point where the wire coming from the main fuse relay box popped off the positive terminal. Ive tried to electrical tape it back on but it pops off if the battery moves around to much and my whole car shuts down. Whats the best way re secure it to the terminal. Looks like it was welded in some way before. I can take pictures if needed. Thanks!
