Fusible link questions...

[Hardrocknc]

Damn this group is good...but I have a burnt fusible link. I may have it tracked down to the alt/regulator. I have searched some other posts on this subject but am still confused a bit. My terminals are still good so I may only replace the link wire. It appears this circuit is 10 ga. wire so I'm thinking the link wire should be actual fusible link wire in 14 ga. I may not use the fusible wire and just install a circuit breaker which will be the square type or slow blow or whatever you call it. Is the 14 ga. fusable link wire the correct size? How many amps actually run throught this circuit assuming the charging is working correctly? What size circuit breaker should I use if I go that route? Thanks for the help.

Oops. I for got to add this a '78 fj40. The only add ons are a radio with a small amp. I also have a couple driving lights wired through a relay off the battery.

Can't answer - but, if you want a great fusible link, contact coolerman (here on MUD) - here's a link to his page http://www.globalsoftware-inc.com/coolerman/fj40/WiringHarnessAdapters.htm

A fusible link is not a fuse. A fusible link protects the part of the harness before the fuse block.
It is able to carry more than the sum of all the fuses together and can deal with big run in currents where a regular fuse or circuit breaker will blow or flip.
Those fusible links are there for a reason. Use a piece of 14 gauge, use the special cover of the old FL and be happy with it.
Note: Fusible links have a special heat resistant non burning insulation. You can buy it by from the roll at a good car electric shop.
AWG14 = 2.0 mm²

Listen to Rudi, get the real fusible link wire...

My buddy’s 79 FJ40 won’t start. Asked him to take picture... WTF ?

That is the fuse holder for the ammeter.

if anyone needs fuseable link in a pinch, o'reilleys carries 14ga and 16ga on the shelf. id guess the other box stores have it too.
