Q:

Solenoid Kit did not make the LT 2000 19.5 OHV start.

A:

Thank you for your question on the tractor engine not turning over to start.

There are a number of things that can cause this to be the problem. If I understand you correctly you are stating that the engine will not spin over when you turn the key?

Please make you have the clutch lever in and the PTO switch in the off position.

The engine model number is a composite of a string of numbers in order to look up parts or a manual.

I believe your engine model number is: 31p677-0804-B1. With that information you should be able to pull up at least parts information.

The start solenoid wire may not have to be grounded if the bolts that secure the solenoid screw directly into the chassis.

The Model number of the tractor is under the seat and the format will look like this: 247.2XXXXXXX or 917.2XXXXXX.

In looking at the picture you sent I looks like it may be a 247.model that has the fuse in the back under the seat below the battery box.

If you would please reply with this number I will be able to look at the breakdown of the tractor and not just the engine model number. Once you have the tractor model number you should be able to look up the manual information.

In the meantime please check the inline fuse in the wire harness under the hood. Some off them are located in the wire harness under the steering area and other models are located next to the start solenoid. It usually is a yellow 20 amp automotive type fuse that plugs into the harness.

Please let me know what you find out.

Thank you for the update on the starting problem. Did you find the fuse? To see if the solenoid is not engaging you could jump across the two red terminals with a large insulated handel screw driver to see if the starter will engage. If it does then you will need to see why the start solenoid is not getting 12 volts through the safety circuit and engage the solenoid. If you do not find the problem please look under the seat of the tractor and reply with the model number of the tractor. Sam A.

Q:

Engine replacement

A:

Thank you for your question.

Without the model number of the tractor, I am not sure where to connect the wires from the engine. The red wire from the engine is the charging wire. The gray wire should be the 12-volt supply to the solenoid on the carburetor. The black wire should be the kill wire. You want to follow the black wire. If it is the kill wire, it should be connected to the ignition coil. If the black wire connects to the bottom of the carburetor, it is a ground.

If you could reply below with the tractor model number, I will look up the wiring diagram. Once I have that I can tell you where to connect the wires.

Thank you for using Manage my life.

Ron,

Thank you for adding the model of the tractor. Over the years, we have sold a few different models of the YS4500. These models had different engines and wiring harnesses. What I really need is the model number under the seat of the tractor. Once I have that, I can tell you what wires should be connected where.

I hope to hear from you.

Ron,

Thank you for adding the model number. The wire on the A1 terminal on the ignition switch should be connected to the gray and red wire from the engine. The orange wire for the lights should also be connected to the A1 wire. The black wire from the engine should connected to the black/white wire from the tractor harness. This should be all the wires.
Please let me know if you need further assistance.
Thank you for using Manage My Life! Mark T.

Ron,
I looked up the part number for a muffler that has a single cylinder engine. The part number for the muffler is 137352 and can be ordered from the link below. To reduce the chances of back firing, turn the engine off at full throttle. This is what the manufacturer recommends.

Please let me now if you need further assistance.
Thank you for using Manage My Life!

Thank you, Mark T.
