I have a brand new 2016 Spyder Rs that I haven't even driven yet. I put in a handlebar mounted radio and have a strange problem. (It could have been there before I started the install and happens whether or not I disconnect the radio power). When I turn on the motorcycle power, then shut it off, I hear a high pitched electrical noise from somewhere in the bike. The only way to shut it off is to disconnect the battery. It then stops, I reconnect the battery, don't hear the noise, and then when I turn the key and shut it off, it starts all over again. I let the noise go on for about 5 minutes to see if it stops itself, but it doesn't. Any suggestions????
