I'm having trouble finding a source for fuseable link wires on line. Anyone know of a source? SCENARIO: About 20+ years ago, as a result of installing a late-70's/early 80's Delco internally-regulated alternator in my stock '72 Skylark, I purchased a modified version of a reproduction engine bay wire harness from local supplier M&H Electrical Fabrication Inc. The modifications I asked for included (1) wiring compatible with the internally regulated alternator, (2) addition of a "power on" wire to support an electric choke and (3) replacement of the ignition resistor wire with one that routes a full 12v to the coil to support my new Dave's Small Body HEI distributor. Installation of the wire harness was remarkably easy and it performed flawlessly. Since I now had a useless voltage regulator on my firewall, I got this brilliant (in my mind, at least) idea to remove the stock components from the regulator and replace them with a 1-stud terminal strip. I then ran a 10-ga wire from the large terminal on the starter solenoid up to the 1-stud term strip in the voltage regulator. Thanks to those efforts, I had a 12-volt source conveniently located (and hidden) on the firewall. BTW, I spliced an appropriately-sized fuseable link to the end of the 10-ga wire that attached to the starter solenoid terminal. Fast forward to now: With the almost finished installation of a BBB in my Skylark I decided to install a new reproduction wire harness assembly. I want to assemble a new, slightly longer 10-ga wire and fuseable link wire combo for installation in my Skylark. PROBLEMS: Not only do I not remember where or from whom I purchased the fuseable link all those years ago, I also can't seem to find a source of them now. I also don't remember the rules-of-thumb associated with choosing the correct gauge fuseable link wire. Your help will be greatly appreciated. Thank you. NOTE: Since Google, Summit, etc didn't seem to know the difference between fuseable link wires and circuit breakers, fuses, etc, I attached a photo of the fuseable links (ID by a small piece of green masking tape) in my new engine harness.
Dan, a fusible link wire is 4 gauges smaller than the wire it protects. The stock Main feed wires are 10 and 12 gauge. The fusible links are 14 and 16 gauge respectively. If your additional wire is 10 gauge, use a 14 gauge fusible link. NAPA sells them. https://www.napaonline.com/en/p/BEL784692 https://www.napaonline.com/en/searc...s-and-curcuit-breakers/fusible-link/211133642

Wow!!! That was fast! Thank you Larry and John for helping this semi-senile old man out. EDIT: Oops... You too, Michael. Your response was posted while I was thanking the other two board members. Sorry about that.
My 12v fuseable link is only supplying 6.2v to the coil when it’s hot. I’m running Petronix ignition I . The KVA @ the ignition wires is 1/2 of what it should be. My schematics show the purple wire off the starter as the fuseable link. It’s a 69 400 Where is the fuseable link situated?
The fusible links have nothing to do with your coil voltage. The fusible links are built into the two main power wires that attach to the big lug on the starter solenoid, along with the + battery cable. They act as main fuses for the power wires. The purple wire is the solenoid wire and goes on the small "S" terminal of the starter solenoid.
