Healthy fusible link photo (2 Viewers)

[Hammer45]

Howdy again from central Texas. Does anyone have a picture of healthy appearing wiring coming from the positive post of the battery to the fusible links so I can repair mine with a close approximation of the original?

Why not just buy a new one? They're still available from the dealer.

I’m learning that there are lots of ways to skin this cat. @ToyotaMatt sent me a new post with 2 ring connectors and a fusible link already in place. I think the supplied one is supposed to go to the yellow wire leading to the EFI. I suspect the blue which is a larger gauge will need to have the o ring removed then split into 3 wires to go into the larger triple FL. And the black should also have the o ring removed and attached to the large gauge white wire that I think goes to the headlights eventually. #1 is what I have on the vehicle and #2 is the new post sent from ToyotaMatt.

Seth that looks to be a connector between 2 different fusible links. Or is that an illusion?

Thought the FJ62 links weren’t available, just the 60’s. Mine is a 1989 FJ62.

That connector is the fusible link. I posted the 60 version. But those 3 wires are the "fusible link". the idea being that in the event of a problem they fail and you replace that piece.

FJ62 Fusible link wire gauges

Those that know me know that I own an FJ40. That means I know nothing about FJ62 wiring! I have been asked to build fusible links for the FJ60/62. I have found a source for the connectors/terminals in Japan, and have fusible link wire in 14,16,18 and 20 gauge. What I need help with is what...

That is the thread I have been looking thru. Just hate to cut off those pretty o ring clamps to fit into that triple FL

 

[Hammer45]

I think I am missing a FL that protects the white wires that go to the alternator. They are pretty heavy gauge and the manual states the fusible link is a 1.25B FL. I’m not sure what size fuse should go here.

FJ62 Fusible Link Fuse Equivalents?

I'm in the process of conducting open-heart surgery on my 3FE wiring harness and one of the things I want to change while I've got it opened up is to replace the 30+ y/o fusible links with something more modern. I've found a couple potential battery mounted power distribution boxes that might...

The colour chart in that thread is correct.

IF you decide to use a fuse, then I strongly suggest a MIDI fuse, they are designed to be slow blow and will mimic a fusible link. A standard ATO/ATC etc is fast blow and isn't appropriate for a fusible link replacement.

cheers,
george.

89 FJ62 here too.... I discovered, to my embarrassment after 2+ years of driving, that the PO put the alternator fusible link back together ... with electrical tape. that's when i learned, yup, there are no easy answers here. at first, i took 16 gauge fusible link wire and fabricated replacements. but that felt just as hacky as what the PO did (i get different answers from different folks but my math led me to believe 16.5 gauge would be the closest to 1.25 mm^2). so i bought the FJ80 version and clipped out the alt wire from it, as that's 1.25 mm^2, and i'm using that instead. so far so good :crosses fingers:
