So I have had my 81 gl500 silverwing for a couple months now and have not had any issues untill this morning. When I turned my key to the "On" position nothing happened. No lights or any indication that my bike had any power. My initial thought was that the battery was dead until I turned the key to the "Park" position and everything lit up as it should. I then started the bike with no problem and I even drove the bike to work in "park" (is that bad?) Anyway I looked at the fuses and there is no visible damage to any of them. All the lights work and the bike is totally operational in "park". I turn the key back to start and everything dies. I did have the bike on my battery tender all night last night for the first time could this have caused the issues I'm experiencing?
