Pulled Goldwing out of the garage this morning (2014 comfort model with Motor Trike Conversion). Checked the CB with the other rider going with me and dash display screen went blank. Other rider said my lights were dim when I pulled out of the garage. Turned off the Trike and when I tried to restart it was dead. Tried jumping but couldn't get anything. Put on Trickler Charger and it said bad battery. Took battery to auto parts store. They checked it and said battery was OK, but bought a new one anyway. Hooked up positive terminal then when I touched the negative cable to the battery it sparked and sounded like the starter engaged even though key was off. Tried again with kill switch in the Kill position and same thing happened. Motorcycle trip turned into a car trip. Any ideas of what is wrong?
