LTX1040 - Blowing Fuses When Connecting Battery

Hello - I have a LTX1040 riding mower (13WX90AS056 - Model #), and everytime I go to reconnect the battery (positive first, then negative), once I get to the negative, I see small crackle sparks, but it blows the 20 amp fuse. I did previously remove the solenoid, and unplug the ignition switch, then put them all back on the mower, and now I am running into this problem. I examined all of the wires, and I do not see anything exposed that would short to ground. Could it be the ground cable running from the battery to the solenoid? Cannot figure out why it's sparking/blowing the fuse.

The battery reads 12.5V, and when I test the voltage at the fuse holder, it is also 12.5V, so something is drawing power?

Okay first disconnecting the engine harness as you may have a stator that has a bad diode or bad voltage regulator. Without the engine info not sure what you have there.

I took off the flywheel, saw black magnetic fragments, which led me to believe the magnets were not attached anymore. They're PULVERIZED!!! And the stator looks like it's been through a war. That could have been causing a short, possibly?

I would say so.

"Could it be the ground cable running from the battery to the solenoid".....this could be your problem!

Could you post some pictures of the magnets and stator?

That is a lot worst than I suspected but I know when magnets turn loose they do a lot damage. Pull the stator and see if the mounting posts are still intact. If still intact then it is a new stator and flywheel time. IF the posts are broken then it is probably time to replace the engine due cost involved vs replacement.

And to add to Stars post, usually a fried stator takes the rectifier out as well so replace it.
If you hook up a good stator to a badly fried rectifier you can burn it out pretty quick.
There are a lot of courage flywheels out there so you should be able to get a good used one
You can not use a Command flywheel because the Commands have a forged crankshaft which is thinner so the hole will be too small .
