What do you think about these leads?

I was chasing down a spark plug issue (my guess is in going to find a high resistance across my top #1 that was replaced in 2014 when chasing down a Slick mag issue (thank you for your quality products Champion), but testing will tell.    Anyway I wanted to test resistances across my aging leads.  All leads in the harness tested with resistances of between 46-56 Ohms.    I flipped the cap over on a whim and found the shielding to be frayed to the #1 bottom.  The plastic appeared intact and I could wiggle the lead without any appreciable change in resistance, indicating that the conducting wire is intact. 

I think I am inclined to replace the leads but wanted to make sure I'm not making a mountain out of a molehill.  So I wanted to gather some wisom...

Thanks,

Brad

Nice of you to check... Since all the resistance was the same, I don't think there is an issue. I have seen worse fraying of leads. Pretty common for that first layer to ware. There are high tension lead testers available, but the problem usually is in the mag or plug. I would be more interested in testing the plugs, and varifying the mags are working properly, before I replaced the harness.

It looks like it is just the top layer of silicon that has rubbed a little and not the actual shield.  The top layer is mostly to help keep the wires clean and prevent oil from soaking into them. The picture only shows a small section of the harness, but other than the silicon rubbing it still looks pretty good.  If there is any extra length in the lead you can cut the end off and reinsert it into the cap if you have the proper tools.  Slick sells a kit with a special pair of modified vise grips for reattaching the mag ends, but they are expensive.  Perhaps a local mechanic has the tools, harnesses are expensive.
