What to use to replace fusible links by starter?

    Hi folks,
    Need to replace those two fusible links that go to starter solenoid. Looks like GM just used those nylon "barrels" to neck down a thicker wire into a thinner one, for the last 4" of wire. But is the last bit of wire a "fusible" wire? In effect, do I need to replace it with a piece of fusible wire? If so, what amp?

    I am thinking that it is just regular, albeit thinner, wire and, thus, the "fuse" part of it was just due to the wire being thinner. Thus, it would melt (blow) before the thicker wire used in the rest of the harness.

    Thanks in advance!

    Wizard,

    Thanks, as always. I will order the Dorman ones from O'Reilly, #85622 and #85627. So, just to confirm, the "fuse" is the fact that the wire is 4-sizes small and thus will be sacrificed before the larger wire? If so, that is the little "black square" on those Dorman wires? Is there a fuse in there, as well?

    Thanks, again.

    I'm pretty sure the insulation on fuse link wire is thicker and softer/different than regular wire. Seeing as it is sold as fusible link wire, there may be other differences as well, such as the size of the strands.

    I think its aluminum wire which has a lower melting point .

    The 85627 is a Chrysler number. The 85622 looks like a Ford style

    You need 85620 and 85621 which are the GM ones

    Well, I thought Larry, The Wizard, had me straightened out, so I ordered the Dorman Fusible Link wires that he posted. Nothing special about them, it seems, tho they do have a black "tang" rectangle sort of thing. Not sure what that is for. Still, I assumed, as Larry said, that the smaller size of the wire would make it "sacrificial" in the case of an overload. Are the aforementioned GM wires (85620/856210) still available? If so, what would be the advantage to using those over the Dorman that I have ordered?

    Thanks!

    I don't think it really makes a difference. A 14 ga. fusible link is a 14 ga. fusible link. They may differ in actual appearance, but function is the same. Unless you are worried about Duane inspecting your fusible links at a concourse car event.:D

    Could happen!! You never know. And then where will Ranger be huh?? With a point off his judging sheet that's where. Larry, how could you!

    I think the GM ones have the correct size ring terminal.

    Hi guys,
    Thanks, again, for all your help. You will not want to order the Dorman ones. One of them had a wire loop that was too small to fit over the solenoid, the other one didn't even have a loop. Napa stocks ones with the larger loop, probably just like GM.

    The Dorman ones work just fine. The part numbers you got were for Ford and Chrysler. You needed to order the numbers I posted
