Question and Answers

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.

Mark

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.

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.
