EMI / RFI and setting timing = problems

Art had commented about grounding shields, yes this harness has only 1 lug end but others have exposed wires or cable that some people connect to ground. By connecting both ends of a shield to ground you can actually induce EMI issues. If you have connected the lug on that cable to ground then that is correct. Most older MSD systems would work perfectly with an unshielded crank trigger jumper or pickup when they introduced the digital systems unshielded wiring caused lots of problems.As I stated earlier, the switch from analog to digital systems opened up a lot of issues for quite a few racers.
