Default Re: Wire Shielding EMI or RF Noise?

I’m using copper tape as a shield on the cam signal, crank signal, and their shared signal ground. All 3 wires come out of distributor together along with 12v power and I have the shielding grounded at one end only. I separated the 12v wire right out of distributor as close as I could and put a ferrite bead on it. I also put ferrite beads on water pump 12v, alternator charging wire, and twisted the coil pos/neg wire from ignition box to coil and put one bead on the twist. Am I using them in the right spots? Should I put ferrite beads on the already shielded signal wires also? Thanks.
