I'm looking for some ideas to squash an ignition noise issue I'm having. I'm able to isolate the noise by shutting off one ignition and the noise goes away. The noise is a steady tick tick tick noise that has an increase in cadence as rpm increases. The oddity is that If I turn on my aux input battery powered bluetooth module, the noise goes away.
Things I've tried are:
1) ferrite cores on the power leads.
2) two types of noise filters with the offending ignition power wired through.
3) replaced spark plugs (using solid tipped automotive spark plugs)
4) Ohm tested each of the ignition leads for proper resistance. They all checked out to show appropriate resistance for the given length. I also slightly twisted and rotated the leads as I checked the ohm reading to see if anything seemed amiss.
5) crimped each of the spark plug connectors to ensure good contact.
6) put dielectric grease on each of the spark plug caps.
7) checked the spark plug gaps.
Any other ideas any0one might have?
