I have a question about the H/D trickle charger..I replaced the battery with a new battery since I don't ride very often I hooked up the trickle charger the red light came on and stayed on..about two weeks later I noticed the red light was blinking??? so I unhook it from the battery and the light still stayed blinking so I unplugged it from the wall. This is a factory trickle charger, I thought I could leave it on year around? Am I wrong in this thinking? Why does the red light blink? It for a 2007 ultra the old battery died and I replaced it with a new battery.
