Follow up: Charged battery for hour and cranked right up. Battery is new from end of last summer. Any chance I have a charger/rectifier issue since I just ran ski the day before? There are no accessories that stay in without key right?
Start the ski and get a meter on the battery. At idle it should be around 13.5. Rev it up and it should go to upper 14's. If not, then you have a charging issue.
