Engine whine through Sirius XM radio

Post by Kenr57 »



I have installed the Sirius XM radio on my 2003 Honda Goldwing 1800 using the auxiliary speaker connection and have installed all three noise suppressors supplied with the Honda CB radio. Bike has 37k miles. The XM produces a high pitched whine that is directly associated with engine speed. The sound is so irritating that I cannot use the XM. Any thoughts would be appreciated.

The ground loop isolator may work, but I'd look at the grounds themselves. Main ground under the fuel tank, check the ground on the alternator as it can introduce a whine for certain. Good grounds fix a lot of things. Good luck.

Keep in mind that a ground loop isolator uses magnetic isolation to break the electrical connection causing the interference. As such, it is also sensitive to magnetic fields itself. I've seen instances where ground loop isolators made things WORSE, because the isolator itself was positioned too close to ignition coils.

So if putting the isolator in makes the problem worse, try moving the actual physical location of the isolator around until it improves.
