Static in Head Sets 1983 GL1100 I

Postby wrangler90 » Sun Feb 28, 2010 7:19 am

My wife and I can hear static in our headsets. This static disappears when I apply the brakes. So I assumed it was a poor ground and ran an extra ground from the battery to the fairing amplifier. This did not change the problem. What can I do next to trouble shoot and fix this problem. Thanks

The static is because of the high voltage in the electrical bus - you'll notice it is more prevalent when the engine is running at higher RPM's. For some reason, at higher voltages, the radio/intercom system is less able to suppress alternator noise. The reason hitting the brakes lessens the noise is because the two brake light bulbs draw enough power to drop the voltage somewhat.

I mitigated (but have not yet solved) the problem by putting two 35-watt driving lights on the front of my bike. This serves the dual purpose of lighting up the road and making me more visible, and drawing down the voltage to kill off some of the static.

You can read more about it in this thread: Eradicating ignition noise in intercom
