Re: L130 blows 20amp fuse after engine runs for several minutes

David : If you have access to a digital volt ohm meter it would be helpfull.

First of all charge your battery really good for quite a while at low amperage, say about 20 amps for several hours, if the battery gets to hot to touch or 120 degrees turn the charger back a little. After you have a full charge on your battery then just set it into where it goes and hook up the posative cable only. Make sure your battery is up to 12.5vdc or better. With a new fuse in the system and the key switch in the off position touch the ground cable to the - on the battery lightly and look to see if there is a spark, this would indicate a current draw when the enginge is in the off position. 20 amps is alot of fuse to blow on a mower. If there is a current draw on the system, unplug the voltage rectifier regulator and again touch the ground lead to the battery ground and see if there is a spark now. Repeat that until you finally unplug the one that makes the current draw go away.

What doesn't make sense right now is the fact that I thought all John Deere models have a battery charge indicator of some kind on the dash and if that light is not going on prior to the fuse blowing you may have a bad regulator rectifier or battery.

Try to short out the fuse without running the engine, just keep touching the fuse if there is to much of a draw it will progressively get hot, until it blows.

A meter is always a big asset to keep around.
