If a fusible pops , testing for a short must be done or it will just pop the new fusible. There are better ways of testing, an inline fuse for example.
the low amp wire is for testing for shorts only. 5-10 amps is used to protect the rest of the harness.
But yes non flameproof wire can catch fire, so when testing you have to watch it and get ready to snip it.
Check all the fuses, and until you get the fusible link, you can remove the old one [ones] and check them for continuity. You can replace the old bad fusible with a piece of approx 5-10 amp wire temporarily , but watch it , if there's a short, it will get hot quickly.
good luck
I went searching ebay for 80 boosters after I saw this post and found this dual diaphragm 70 series booster.

Sounds cheap. Have no idea of quality.
My 73 brakes are woeful . I will get one of these and report the results.
If you get the starter working again, get a current draw test when cranking. That should tell you the condition of the starter.
I'm pretty sure the new geared starters for f/ 2f engines fit the 80 3fe.
If you squirt a bit of wd40 in the weep hole it can quieten down a bad bearing temporarily. Not a permanent fix, but can sometimes tell you if you have a bad bearing.
Won't tell you if the impeller is scraping due to in/out play though.
Also, when my primary jet clogged, I could always limp home with my foot down and the secondaries would keep me going. It might pay to check out your secondary vac diaphragm too.
My main primary jet blocks from time to time. but it usually still idles ok. Make sure there's power to the solenoid and it clicks when powered. It's easy to clean the solenoid and blow out/flush where it screws in.
another possibility is water in the fuel.
When that happens it will idle and that's about all it will do.
You can try cleaning the end of idle/fuel stop solenoid and blowing out where it screws in.
Yes it does. I "think" in australia from 1985 onwards the fj60 was called the fj62 and had the 3f carb engine, available in manual or auto. We never got the 3fe until the 80 series.
The new leads might have too much resistance for your ageing igniter/coil. You can try using the old leads until you get the igniter /coil sorted.
The 78 to 87 igniters are interchangeable. see here Dizzy FAQ - http://www.globalsoftware-inc.com/coolerman/fj40/DizzyFaq.htm
Also it doesn't have...
One thing to quickly try is run a wire from bat+ to coil+ temporarily and crank it over ,and check the spark quality. If it.s still weak it could be a coil or igniter issue.
***The 1980 has a inline ballast wire in the harness rather than a resistor, and can make things confusing.
