Yes, that meter should give a reading on a 5 ohm resistor on that setting so it suggests there isn't one.



Yes the lead will work fine well with your bike. It might make radio frequency interference which wont bother you at all unless you are using headphones on your bike but might make an annoying buzzing on peoples car radios and a snowstorm on their TV screens as you ride past.

Horses for courses?, NGK info relates to modern bikes?, Magneto = no resistor, points ignition = 5k, CDI = whatever the maker advises.

Now here's a thing.The current HT lead on my bike with NGK plug cap and provided by our hosts reads 5k.ohms.Now I am assuming that's for a standard 2003 bullet 350 with distributor/points.My bike was bought with electronic ignition fitted.Its running ok but is that lead compatible.

Yes, no problem, a resistor is not critical and is used as an RFI suppressor, you bike will be quite happy to run with or without it. Modern ECU equiped bikes would not be happy though.

Not just modern ECUs, either - the instructions for my Sparx reg/rectifier unit also state that the ignition needs a suppressor plug cap otherwise the interference will kill it! As my nearly finished project is also fitted with a BT-H electronic (CDI-based) magneto, whose instructions insist that I should only use a NON-suppressor plug cap, it looks like I have a bit of a problem on my hands. ( We'll see how everything works with an Iridium (ND, not NGK) plug which has a resistor, and a non-suppressor plug cap.



Failing that, can you get Faraday cages for reg/rectifier units?

Thinkng about it, most reg/recs effectively ARE in a faraday cage, that being an earthed, metal enclosure. So any signal "noise" would be entering them by induction in the wiring. So to prevent it, you'd need to use shielded cables to and from it. But I do wonder what componant in a rec/rec is going to be affected by RF?

" But I do wonder what componant in a rec/rec is going to be affected by RF?". A MOSFET, possibly?.
