Default New to me ltx 1042

I bought a cub cadet ltx 1042 at an auction last week and after changing the battery I got it running. But it’s running kind of rough and I’m just running down and fixing small issues here and there.

I have found a couple wires that are cut and I don’t know where they go.

First model and serial #

Mod. # 13AX91AR010

Ser. # 1E199H60092

1. I have a red and green wire wire running next to each other to the carburetor. Red wire goes to the carb. The green wire isn’t hooked to anything. It has an insulated wire connected at the end but nothing attached.

2. Under the battery there is a large wire loom (coming from the engine area and there is a red wire coming out of the loom and into a plastic connector. Then a yellow / black wire comes off that and isn’t attached to anything.

3. There is a green wire near in the same are as the yellow and black wire that looks like it may be a ground but I am not sure.

I looked at working schematics but I couldn’t follow it very well.

Anyone have any ideas?

May not actually be electrical at all. What kind of engine does it have? 1 or 2 cylinders? If it has 2 cylinders the issue may be that it's running on 1 cylinder. There are a few things that can cause an engine to only run on one cylinder instead of both.

Before getting into specifics, what brand is your engine and how many cylinders does it have? Some pictures might help too.

Oh, well in that case, running rough on a single cylinder engine can be caused by lack of proper air, or proper fuel, or also by improper spark timing. The electrical system doesn't have anything to do with the engine receiving spark, the coil does that without need from any external power.

Make sure the air filter is clean and if it is very dirty replace it, and remove the carburetor to make sure all passageways are clear of any debris. Any sort of debris in the carb can cause a blockage, restricting fuel flow to the engine. Simply blowing compressed air through all the passageways usually does the trick.

That being said, rough running could also be caused by the spark being improperly timed. Check and make sure that the coil is facing the right direction and is properly gapped to the flywheel (.010-.020 usually is good), but also remove the bolt that secures the flywheel to the crankshaft and check to make sure that the flywheel key is not sheared. The key slot on the flywheel must line up perfectly with the key slot in the crankshaft. If they are not aligned, remove the flywheel and replace the key.

I do not have much experience with Courage engines any more than a general understanding of how an engine works and what causes it to not work properly, if it were an old Briggs and Stratton or Kohler K series it would be easier to identify the problem. Hope this helps though

green wire is for the oil pressure sensor that most of them do not use, ground it and the oil light will be on all the time

2. Under the battery there is a large wire loom (coming from the engine area and there is a red wire coming out of the loom and into a plastic connector. Then a yellow / black wire comes off that and isn’t attached to anything.
no idea there probably not an issue

3. There is a green wire near in the same are as the yellow and black wire that looks like it may be a ground but I am not sure.
again probably not an issue

I looked at working schematics but I couldn’t follow it very well.
a schematic for your tractor will not show the unused wires

Anyone have any ideas?
as for rough running I'd clean the carb and adjust the valves before anything else

Agreed.

Don't know how I forgot to mention valve adjustments because that's important!

Sounds good. I have a new carb coming in tomorrow and adjusting the valves as we speak.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
