Yamaha IT 175 1982 got no spark?

I can't diagnose a motorcycle problem over text. However, I can guide you through some common troubleshooting steps for a "no spark" issue on a 1982 Yamaha IT175.

Important Note: This advice is for general guidance only. Always refer to your owner's manual for specific information and safety precautions.

Here's a breakdown of the likely culprits and how to test them:

1. Ignition System Basics

* Spark Plug:

* Check the spark plug itself: Is it corroded, fouled with carbon, or damaged?

* Clean or replace the spark plug.

* Ensure the spark plug gap is correct. (Consult your manual for the correct gap)

* Ignition Coil:

* Inspect the coil: Look for cracks, damage, or loose wires.

* Check the resistance: Use a multimeter to test the resistance of the coil. (Your owner's manual will provide the correct resistance values).

* Ignition Module:

* Inspect visually: Look for any signs of damage or corrosion.

* Kill Switch:

* Make sure the kill switch is in the "run" position.

2. Troubleshooting Steps

* Battery:

* Check the battery voltage: A fully charged battery should have around 12.6 volts.

* Ensure the battery terminals are clean and tight.

* Wiring:

* Inspect all wires and connectors: Look for chafing, corrosion, or loose connections.

* Check for continuity: Use a multimeter to test the continuity of each wire in the ignition system (refer to your owner's manual for wiring diagrams).

* Stator:

* Inspect the stator: Look for signs of wear, damage, or corrosion.

* Test the stator: Use a multimeter to check the output of the stator (refer to your owner's manual for the correct specifications).

* Flywheel:

* Make sure the flywheel is securely mounted and hasn't moved.

* Inspect the ignition pickup (pulse generator) on the flywheel: Look for any wear or damage.

3. Additional Tips

* Ground Connection: Make sure the engine has a good ground connection to the frame.

* Fuel: Is there fresh fuel in the tank?

* Air Filter: Is the air filter clean?

Remember:

* Safety First: Always disconnect the battery before working on the electrical system.

* Consult a Mechanic: If you're not comfortable with these tests, it's best to consult a qualified motorcycle mechanic.
