Unfused HEI wire?
 

I noticed that my HEI wire is plugged into the unfused terminal on the fuse block.
Should I install an inline fuse, if so what size.
Thanks K.E.N.

That's what I did with mine. It didn't feel right going without a fuse.
Here's the one I used, but I see it's not available now: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

The might be good, too:

I have never done a fuse on that ......Ask you a? , did you see the factory fuse that hei? If you understand, why would you worry about a fuse on the ign system? Longhorn:smoke:

As long as that wire going to the HEI,
Does not have voltage with the key off .

Hello,I didn't know that terminal lost power with the key.
Thanks K.E.N.

Not all terminals on the fuse block lose power when the key is off. The one you want is marked "ignition unfused".

On my '70 there were two of those extra unused unfused terminals. I used one for the HEI and one for the electric choke on my Holley.

I put an inline fuse in mine. I remember going bigger than necessary, maybe 10A, so it will never blow under normal use unless it shorts.
