Hey Dale, Thanks for the info. It's been a week since I've been able to get back to this but I was able to bring home my fluke multimeter from work and borrow a battery charger from a friend. The battery read mid 8vdc so obviously it was low. At that reading nothing on the mower would work. No lights, no clicking of the starter, nothing. I pulled the battery and trickle charged it at 12v at 2amps for about 8 hours and that brought the charge up to about 12.7vdc by morning. I replaced the old blown 20amp fuse from before and I hooked the battery back up to the battery leads. I did not notice the sparking as I applied the negative ground terminal as you told me to watch for, and I also waited to see if the fuse would heat up and blow just hooked up with the battery now fully charged. It didn't and after about 10 - 15 minutes I hopped on and turned the key. To my surprise it not only turned over and started, but it kept running more than the two minutes it would before it used to blow the 20amp fuse. I tested the PTO switch (mower deck is currently off) and the PTO engaged fine. I ran the engine for about 20 minutes before turning it off. Could all of this have been caused by a bad battery??? I'll admit,I bought the L130 back in August 2003 from Home Depot and the battery is original which would make it 6 years old. I use the mower in the normal Oklahoma summer months and store the mower in the winter. Never have I had to charge the battery in the past even in the spring. Up until now it's simply been a matter of turning the key and it always started up. Why would a dead or low battery cause the 20amp fuse to blow once the engine is started after a jump start and the engine runs for several minutes? I worry because I jumped the mower's engine 3 or 4 times with a running car's battery which I've since heard is a BIG no-no due to the amperage difference. If I buy a new battery and it discharges after a mowing or two, can I assume the voltage regulator/rectifier or stator could still be bad???? I'm fearing the worst that I still haven't gotten to the bottom of all of this and I will once again fall into this problem. Or do you think that maybe just because the battery was 6 years old, that simply replacing the battery will permanently resolve the problem?
