My question is this: Can I have an effective fusible link from Positive battery cable to junction block, WITHOUT replacing the positive cable?? Just finished hooking up my new forward lamp harness in my '68 (Thanks Jimk,& John for voltage regulator plug help)!, and discovered car has no junction block, but the way previous owner had it wired up everything was working! I can go into detail of how it was wired if needed.
Can I order a junction block, mount it to radiator support, connect red 10 gauge wire from harness to it, then run 14 gauge wire from positive cable post down to the junction block? Will it be effective? As a fusible link? The reason I'm asking is it looks like it would be a bear to get to where positive cable hooks onto solenoid to replace the cable. 396, with factory air, and headers.
I'm more interested in functionability, and safety, then originality. Please advise! New to all this- Al

I would do pretty much what you suggest except use about 6” of #14 fusible link wire (regular wire is not a good substitute for fusible link wire) spliced to #10 wire to connect from the battery to the j-block. Of course disconnect and remove the other power supply wiring. As to replacing the positive cable. If you can connect the #10 wire to the existing cable it should be ok. I understand the hassles associated with changing the positive cable but it would be the best way. You can also just replace the cable clamp.

I agree with the last post. Both 14 ga wire and 14 ga fusel link will work, but the fuse link has a special insulation that will stay intact when the wire inside melts, the regular wire will burn thru the insulation and possibly cause a fire. Under no circumstances should the fuse link be located in the passenger compartment, since it will give off a lot of smoke when it lets go.

Thanks Al for responding to my topic of diagrams.I agree with the first response to your problem 14 gauge wire would be suitible for that application, and as hard as it may be to fight your way around in there, changing the cable sounds like the best route to go, saving you heart ache in the future! good luck
