I have a 1969 Lemans conv. Original harness had a fusible link in the power feed cable, I removed the fusible links and ran new wire. My 10 Ga power feed wire had a lot of splices in it.The fusible link is a smaller Ga wire. Will it cause any problems by not haveing them installed. (DK GRN TO RED AND BLK I think it was RED)
About 15 years ago I put a Delco HEI out of a 1975 wagon or somthing like that. I thought I would change it out with new HEI ,I bought CRT Performance HEI and it will not run with it installed the + battery cable gets Hot and fire shoots out of the carb. I reset the timing twice no help. I put my old delco back in and it runs fine.
I noticed when I was running new wire .I have a 14 GA BLK wire going to the bat side of the distributor this dose not seem wright. I found a cut wire BLK PINK or BLK Orange 14 GA I don't remember wright now located under the voltage regulator wire bundle. Tat seem more like the correct wire to run to the bat side of the distributor. I also have a in dash tach that has never worked what color wire goes there.
I still have to conect the red 10 ga to the starter,as soon as I do that I will check voltage to the distributor.

First of all, the fusible link was a factory device that would protect the power feed cable in case of a hard short in the car's wiring. It typically was a short length of smaller gauge wire as you describe.

It's always good to have protective devices in electrical circuits so I recommend replacing the fusible link, if possible.

You could try to find a suitable fuseholder and fuse to use instead; the fuse rating should be slightly above the output rating of the alternator. Perhaps the car audio afttemarket has suitable fuses, used to feed the high-power amplifiers.

Your black wire to the HEI BAT terminal was probably installed with the HEI conversion. Check to see if it has 12 volts with the key in crank position and in run position. If it does, than you probably have the HEI wiring conversion done already.
