So, I have a 2007 Cub Cadet LT1050 and it has been blowing the fuse lately.
It has only blown the fuse when I am mowing, but I mostly mow with it. Monday I was hauling the trailer with tree trimmings on it most of the afternoon and then started mowing. I was one round in when the fuse blew. Seems to always blow on an incline if that matters. Also, once it blows ,even if I let it sit, and replace the fuse it will blow as soon as I turn the key on. The next day with a new fuse it may run fine for a while.
Things I have noticed:
1: For a while the backup safety has not worked. I used to have to put the key in the yellow arc and push a button so the deck clutch would stay engaged. If not, as soon as I go to reverse the deck would shut off. Now, the deck stays running no matter the key position.
2: I had to clean the terminals for the starter relay because they were corroded bad enough it had a hard time getting a good enough connection to turn the motor over consistently. Thought it was a bad battery at first. Had no issues with the fuse prior to cleaning these.
3: I have noticed this year it has surged at idle a few times I have had it out, but it was inconsistent. I use straight gas, no ethanol blend.
The drive belt, deck belt and fuel filter were replaced a couple years ago. It has 300ish hours on it. Has gator brand blades replaced back then as well. Oil change and grease every spring even though the hours don't require it that often, it is easier.
I am thinking it is either the backup safety relay getting hot and shorting or the stator for charging gets hot under load mowing and shorts. I ordered a circuit breaker to use for testing and will be here Friday.
So, does anyone know the wiring on these to check for shorts the next time it blows the breaker?
The only electric parts I know of are possible a fuel cutoff solenoid, voltage regulator, charging stator, deck clutch (i doubt it can be this if the deck is off and it still blows when I turn the key on), the lights (which the local Cub guy said it could be but did not find any issues but is a known problem), and the backup safety relay.
Am I missing anything?
