On my 3500 diesel dually, there are 5 bolts on the upper left side of the firewall. They each have a fairly heavy wire attached to them. Each wire has
a white, round fuseable link in line before joining the wiring harness. One of those fuseable links finally failed. I can't find them, but I did find
a kit at O'Reilly's that contains about an 8 gauge copper wire with an inline 30 amp round fuse inside of a white plastic housing. But as soon as I
installed it and cranked the Cummins motor, the fuse burned. The truck runs just fine with no inline fuse on that line. The alternator gauge shows 14-
15 volts. Do any of you know what amperage this in-line fuse should be? Thanks for your comments.
