I have a 2007 GL1800 Trike that I am getting ready to sell because of health conditions. When my wife parked it two years ago it was working perfectly. I used a battery tender and the battery is still holding a charge and the bike will start. However, the radio will not turn on at all. Nothing. No radio display on the LCD screen etc, Also, the turn signals will not work. When I push the turn signal button for left or right turn signal the left turn signal light will come on, but it never blinks. Also, I can hear the three relays that is on the right side of the bike (as you sit on it) under the seat making a noise. Sort of a whining noise. I think those relays were replaced by a guy that was working on a LED light on that side of the bike. I have a brain injury (military injury) so I have a hard time remembering what the guy did to the bike, but I think I remember him replacing those LEDS for whatever reason. Any ideas or suggestions on where to start troubleshooting?
