This fusible link wire going to my junction block appears to be worn on top . I assume the plastic block circled is where the normal wire and fusible link wire are joined ? To replace it do I just cut that normal wire below the block and splice in another fusible link wire ?
Cheers

yes you can use the modern style fusible links https://www.amazon.com/dp/B07426WCLM/

i believe that supplies the power to your dash 20 amp fuse should be just fine

Erroneous information.. A conventional fuse is never used to replace a fusible link..

Replace fusible link with fusible link.

That looks like the same main power wire as my ‘75, which is a 10 gauge wire with a 14 gauge fusible link. These are so common that they are often marked in the Dorman product line as a “GM fusible link”.

If you burn through that link the entire truck goes dead because it feeds the dash and the ignition. Had it happen once when I was at speed on the highway, and then turned on the headlights. Apparently the new high amp alternator suddenly kicked in more amps to feed the headlights and that exceeded the link capacity. Used the LMC headlight relay kit so it won’t happen again.

I just bought a fusible link repair wire from O’Reilly’s last week.

so I have a couple of these fusible links on my truck. Are 2 into 1 on fusible link still recommended? Are they available? Or should I run extra links on each wire to terminal end?

Looking for advice , should a replacement fusible link be installed with crimp connectors or solder? I have found the link that powers the fuse block is dead. so just asking if a but splice is ok to use or if soldering is better?

@Ken B , @Matt69olds or @RustyPile wilk be along here shortly I’m sure and will have your answer. I’d be just guessing. Sorry

The answer to your question depends on your skill level. Are you better at soldering? Or are you better at crimping connectors.

The alloy of the wire in a fusible link is not conducive to solder bonding.. Unfortunately, a well applied butt splice is the only way to join a fusible link to a copper wire..

If that fusible link hasn't blown or otherwise failed in some manner, just leave it as is.. If it needs replacing, remove it by cutting where the two wires are joined.. Install a 16 gauge fusible link on each of the two wires..

Thanks.
Didn't think about the melting temp of fusible link.
Butt splices and heat shrink it is.

That's what I was going to say. Use not insulated crimp but splice with quality heat shrink over it in any area exposed to the elements.

So I went to autozone to order links(not in my store) the counter guy was confused on what it was.....and he wanted to know so I explained it's function and why they are used. He was genuinely interested I was encouraged that maybe he will keep learning and be there for a.minute
Not like others that are totally clueless
