Thanks for your reply
I have taken upper shelteroff. Went back, retraced the radiator fan filters, Pump filter and yes there are a couple of other filters on the engine. Checked all grounds. Basically
I suppose I could live with it, after all its only a 30,000 motorcycle including the extra's. Ha
Not really.
It's my wife the co-rider who has the sensitive ears.
Took a stethascope to the alternator and boy is it loud, but that is the mechanical aspect and not the electrical.
This may be silly but I know in the automotive world, their are Alternator noise suppressors that go between Alt. Post inline with Pos. Cable to Batt.
Anyone out their ever tried it. My Goldwing only has 14000 miles on it and I am very particular and treat electrical items with attention. I have dislocated the add on items to the receiver and that wine goes up and down. A little music can help and turning the intercom mute down helps but a fine line of communication with a co-rider.
I am going to put on a ground Isolation and fuse box just to keep wires off of the Batt.
A little over kill but won't hurt a thing.
Once again this whine is with everything (turned off) XM-disconnected at plug under left pocket, so ground loop is not an issue) except the intercom
Thanks for your input
