HT Wire and RF Noise
There is still one thing I'm wondering about ...
I shielded the HT wire wirh 'Braided Tinned Copper Mesh Sleeving' (like the one from MA) and grounded it (Engine: Zenoah 231).
By doing so I was looking at the two other wires comming out of the first coil - the red one which goes to the second coil and the black one which goes to the Stator Gater.
Do I have to shield those ones as well or is just the HT wire the one that's causing RF noise? Would it make sense to shield and ground them as well?
Thanks.

No.....but make sure they can not move about, so they dont end up breaking through moving...as its possible where they enter coils it will break.

The HT lead is taking a very high voltage hence problems, the feed wire are low voltage, and should not cause problems, i did cover mine with heat shrink for added protection.

Thank you Sparky. I'll use shrink wrap as well.
It's just too bad that you can not access either one of the coils in order to replace any of the wires.
Thanks, again.

I have found a small amount of noise coming from the "red wire" in some installations and this really should not be a big issue. I have however, shielded this "red wire" as well on some models as it does not hurt to do so. The wire to the Stator Gator does not need any shielding at all as it IS a grounded and shielded wire and also has an opti-couple to the receiver (hence- no physical connection).

Hello John,
Take a look at my setup and let me know what you think. Will it work?
Thank you.

It should work nicely. Very neat set-up.
