I have a 99 lazer with the 25 kohler. Now here is the problem, when I go to start the machine in the morning, its dead, its clicks for a bit then nothing, sometimes I don't even get the clicking from the starter. So I jump it to get it going, then its fine for a few hours while mowing, most of the time I can get the day in before I start having problems, oh I never turn the mower off, if I do it wont come back on. Now if even if I charge the mower at night, during the day it wont hold a charge, and maybe a 1/2 hour or so the mower goes to die out, then that's it even if I jump it it wont run with the mower on. Any ideas, I have replaced the battery twice, I dont know where to start???????????????
