At least it's a confirmed fix and you don't have to troubleshoot the JB. I'll guess the battery is $100-125. Last DieHard I bought was $100, an AGM from Advance Auto. My Vulcan and ATV use the same battery.I pronounced the battery dead at 10:16 EST. No autopsy will be performed but we’ll list cause of death as “Kawasaki dealer battery exposed to prolonged single digit weather”
