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???????????????

Did you clean the battery cables and battery posts? Check the fuse?

Sounds like your charging system is not functioning properly.

Take a look at this post and perform the test as outlined to find the likely problem; http://www.lawnsite.com/showpost.php?p=1811563&postcount=4

Ok found the regulator, I don't think I did this right, nor do I think I have the right meter, I put the mete on the only setting that was showing a number, and the number was 4.9 and still going up

You need a multimeter such as this; http://images.search.yahoo.com/images/view?back=http%3A%2F%2Fimages.search.yahoo.com%2Fsearch%2Fimages%3Fp%3Ddigital%2Bmultimeter%26sado%3 D1%26ei%3DUTF-8%26fr%3Dyfp-t-832-s%26fr2%3Dtab-web&w=406&h=495&imgurl=www.ingram-tech.com%2Fproducts%2Fmeter.jpg&rurl=http%3A%2F%2Fwww.ingram-tech.com%2Fproducts%2Fp35761.htm&size=36k&name=meter+jpg&p=digital+multimeter&oid=6b5c0c5bc3172854&fr2=tab-web&no=3&tt=28341&sigr=11e6dc7no&sigi=116fe38cp&sigb=13c9bfbdt

For the running stator test the meter MUST be set to read AC voltage, To test for battery voltage on the center wire at the regulator plug (un-plugged from the regulator) the meter needs to be set to DC volts. This wire should read the same voltage as the battery with the key in the run position.
