I have a 2007 Ultra Classis Patriot model. I bought the bike new. While having multiple summer thunder storms I let it set in garage for eight days last year with out starting. On day nine when I went to go to work the batter was dead. My dealer tells me it was a dead cell and replaces the battery under warranty. Three months latter basically same scenario; this time the dealer keeps the bike overnight and does a charge on the battery and a diagnostic on the charging system. They tell me all is well with the battery and charging system. They tell me that big touring bike with lots of electronics draw more juice sitting still. They suggest that I get a battery tender. I get one, install it, and works well when I keep it plugged in daily. During this summer I had left the tender unplugged for four days. I needed to move the bike for a hurricane evacuation and it was dead again. When I got to my evacuation destination I took the bike to a dealer who charged the battery and did a diagnostic on the charting system. Again with a different dealer he said “Battery and charging system looks good”…. , we don’t see any problems. With the tender plugged in daily I am good to go. However, after the bike not being plugging in for three days last week, the tender has yet to bring my hog back to life after being charging on the tender for four days. The horn won’t even toot, or the lights come on… All I get is the green neutral and oil light. I'm starting to get aggravated. What do you think? This is my first touring model. Is this a HD touring issue or an isolated one? Please advise.
