Had some work done on my Roadmaster by the dealership. Everything was going fine, then due to things going on didn't get to ride for 2 weeks. Come out and its dead. Power button won't work, but for a moment after I hit the run switch the screen came on. It said I had 4 codes. Couldn't scroll, just could read part of one and it said RT battery terminal. It went out again and I haven't been able to get the screen up. Put it on a battery tender for two days and nothing. Bypassed the tender cord and did a direct connect to the battery with the tender via charging clamps. Still nothing, but the head and tail lights came on. They shouldn't because I have everything off. I'm confused as can be. Anyone got any ideas??
