Guest Farmer Wayne Posted November 13, 2017 Share Posted November 13, 2017 Hey everyone! I'm restoring a 72 Buick GS Convertible, with a 455 engine, There are two inline fuses going to the large terminal on the starter, one a little heavier gauge than the other I have never run across those and wonder if I can replace them with replaceable fuses Link to comment Share on other sites More sharing options...

Very commonly used on GM cars of this vintage. Why do you think you need to replace them? And FYI, if you change them for something else, that's not "restoring", that's "modifying". Certainly you can use a maxifuse instead of a fusible link, but again, if the originals are not burned out, why change them? 1 Link to comment Share on other sites More sharing options...
Bloo Posted November 13, 2017 Share Posted November 13, 2017 They used the fuselink wire for reasons of reliability. They can take a temporary overload, years of vibration, etc. better than a fuse. If they are intact, it is best by far to leave them alone. If they are bad, best to replace with more fuselink wire. Fuselinks are typically 2 sizes (four numbers) smaller than the wire they are protecting, for example a #10 wire would have a #14 fuseink. 1 Link to comment Share on other sites More sharing options...

Guest Farmer Wayne Posted November 13, 2017 Share Posted November 13, 2017 One has burned the wire cover off, and they both have corrosion Link to comment Share on other sites More sharing options...
Bloo Posted November 13, 2017 Share Posted November 13, 2017 (edited) NAPA probably if you are in the US. Most parts stores should have or be able to get them. In some cases you can buy them as individual parts with the little "fuse link" tag. Fueslink wire is also available as bulk wire. The whole idea of these is they burn up instead of the harness. A car battery is enough energy to make one hell of a fire. A fuselink keeps it isolated to one spot, and the special non-flammable insulation keeps the melted wire contained.

Guest Farmer Wayne Posted November 13, 2017 Share Posted November 13, 2017 EXCELLENT! Thanks for the great info! 45+ years in the auto-body biz, didn't do a ton myself with the electrics, other than able to follow a diagram, when I needed. I,m in Upstate NY Link to comment Share on other sites More sharing options...
Rusty_OToole Posted November 14, 2017 Share Posted November 14, 2017 Any auto parts store should have the fusible links, at least they used to. With all the millions of GM cars that used them they should be easily available. Link to comment Share on other sites More sharing options...
JACK M Posted November 16, 2017 Share Posted November 16, 2017 I am sure I saw those in a "Painless" or "Ron Frances" catalogue or the likes. Street rod wiring kits. But they all sell individual parts. Link to comment Share on other sites More sharing options...

Go to summitracing.com and enter fusible link in the search there. Edited November 16, 2017 by JACK M (see edit history) Link to comment Share on other sites More sharing options...
Guest Posted November 16, 2017 Share Posted November 16, 2017 Bloo thanks for your #3 post. I sold fusible links for a good number of years when I worked for GM and never had an explanation as concise as yours. Link to comment Share on other sites More sharing options...
