Sparkplug noise in headset

JSTAVONIC, no help here but problem is similar.
My whine worst thru the intercom, varies with RPM. It is coming thru on the radio. I do have an XM but is not currently hooked up. There is a ground loop isolator on XM circuit goin ginto the aux connection.
Also of note is the headlights seem to modulate slight at idle and dim on deceleration. My presumption is hte alternator is going south. Only 28K in 5 years. The bike spent many months in storage at times.
I did a search but not much luck. Seems the alternators normally are pretty reliable.
I will check voltage after this next ice storm clears out.
I had not thought about the plugs.
For reference i have 15K on the Bosch Platinum Plus 4.
Maybe I should check them also.
This whine, really buzz, is mainly on teh ICOM circiut.
I have not been on the AUX lately but it has the ground loop isolator on it.
This buzz just recently came up.

Hey JST...,JSTANOVIC said:
If it's a "spark tick" noise I second Red's check list...
Your term "engine buzz" could also be something like alternator noise,
or a combination of spark and alternator.
The spark "tick" is usually pretty obvious at low RPMs.
If it's not just spark tick,
I would start looking for a loose or dirty ground point
along with checking Red's list.
Hey Oldsman,
When you said...
I immediately thought... Dirty/corroded or loose connections.
That includes ground lugs as well as all the various connectors
that can get corroded over the years.
Sometimes just re-seating some connectors, and re-tightening ground lugs, will cure problems like that.
Of course, the big headache is getting to those connectors to re-seat them. :roll: :lol:
