Help: Fusible Link rating
Hi, I have not posted in awhile. Finally working on electrical problem on my 76. The FUSIBLE LINK from the fuse box to the ALTERNATOR blew and I need to replace it. What is the AMP rating for this link? Any one else have this happen?
I really appreciate the help.

Thanks, well it seems that C3's do not use fusible links and that its a regular wire that shorted and burned through. I was told that fusible links were not used until the early 80's. Can anyone validate this?

The wiring diagram for my 78' does NOT show a fusible link going to the alternator. There are 2 coming from the starter, but none to the alternator.
P.S: how about filling out your profile.

Researched this quite a while ago.
You probably won't find a direct rating. but the Rule of thumb is that you use 4 times the wire size.
12=20 amps, so a 12 ga fuseable link could be replaced by a 80 amp fuse element (a cartridge type fusible link)
Here is a good link http://www.autoshop101.com/forms/hweb1.pdf

There were 4 separate and distinct fusible links in my '77.
I replaced all my fusible links with auto-reset circuit breakers:

I don't want it to loose power until I get it out of the road if I can possibly avoid it.
Also, just about all new cars use these auto-reset breakers, so that's what I did.
They won't re-close until the fault is gone, so if it was an intermittant fault, it will reset and I will regain power.
