Replaced wheel bearing. Temp gauge quit,broken connector wire. Battery light came on a couple of days later,alternator dead. Replaced alt,light still on. Battery cables(pos and neg) had places where they had possibly arced,fixed. Neg cable sparked when touched to post,removed fuse to passenger low-beam,spark stopped. Battery(alternator)light still on.Any possible suggestions? Will retest alt to see if it is still ok. Thanks.
