I have a 240 with a 14 Kawasaki in it. It's been running fine until a couple days ago the battery seemed dead, so I tried jumping it with the battery charger and that wouldn't work. I then put a battery pack type quick starter on it, and it fired right up. I put the battery charger on trickle charge all night, and the battery is reading fully charged, but will not start. I put the battery pack quick starter on it, and it starts right up. Any ideas? Thanks, Denny
