Hi, I purchased a optimate cam bus charger and used it over the winter on my bike that was stored in a detached garage with no heat. When I went to start it for the first time I only saw a red light on the instrument panel for a short time. I took the battery out and charged it . I had the battery load tested and it is good. I checked the 15a and 7.5a fuses, all ok. I was wondering if there is something I'm missing or has anyone else experienced this problem. I purchase the bike in 2018 and have 12000 miles on it and would like put many more on it. I live in Syracuse NY where we have winter season. Any help would be appreciated.
