To check the coil on an ATV, first, ensure the ignition is off and disconnect the spark plug wire for safety. Use a multimeter to measure the resistance of the coil's primary and secondary windings according to the manufacturer's specifications. If the readings are outside the specified range, the coil may be faulty and should be replaced. Additionally, inspect for any visible damage or corrosion on the coil and its connections.

To test the trigger coil on a Yamaha ATV 100, first ensure the ignition is off and disconnect the wiring harness from the coil. Use a multimeter set to the ohms setting to measure the resistance across the coil's terminals; refer to the service manual for the specific resistance range for your model. If the reading is outside the specified range, the coil may be faulty and should be replaced. Additionally, you can check for continuity to ensure there are no breaks in the coil wire.
A Suzuki ATV is a popular model. ATV's are often sold online although one must be careful when purchasing online. Also, you can check local dealerships for ATV's.
Typically, a CDI (Capacitor Discharge Ignition) box generates a high voltage output to the ignition coil, often in the range of 20,000 to 45,000 volts, depending on the system. If you are measuring 116 volts going into the ignition coil, that voltage may not be sufficient to produce a spark. It's important to check the CDI box, ignition coil, and wiring for any faults or poor connections, as these can affect the overall performance of the ignition system. Additionally, ensure that the CDI is functioning correctly and is compatible with your ATV model.

if a motorcycle or atv turns over but won,t start which of the following would be the most probable cause? a. defective charging system rectifier b.defective regulator c.open solenoid coil d.shorted ignition coil
A pickup coil for an ATV may be tested by measuring the resistance across the coil's electrical leads and comparing this value against the expected range specified in the ATV's shop manual.# Disconnect the pickup coil assembly from the ignition system (e.g. the CDI unit or engine control module) # Identify the coil's electrical contacts on the connector # Measure the electrical resistance between the coil's contacts with an Ohmmeter or digital volt meter.Take care not to grab both leads of your ohmmeter with your fingers while measuring this value or you'll measure your body's resistance in parallel with the coil. It's not dangerous but it might corrupt your reading.The value for working part will vary by manufacturer and model, but will typically be between 100 ohms and 350 ohms.If the coil reads as an "open circuit", or the resistance in the high 10's of k-ohms or higher, your coil is damaged and likely non-functional.
