How do you check to see if the coil on a four wheeler is good?

1. Check for spark. The most common way to check if a coil is good is to check for spark. To do this, you will need to remove the spark plug wire from the spark plug and hold it close to the engine block while someone cranks the engine. If you see a spark, then the coil is good. If you do not see a spark, then the coil may be bad.

2. Check the resistance. You can also check the resistance of the coil to see if it is good. To do this, you will need a multimeter. Set the multimeter to ohms and then touch the probes to the two terminals on the coil. The resistance should be within the range specified in the owner's manual for your four wheeler. If the resistance is too high or too low, then the coil may be bad.

3. Inspect the coil. You should also inspect the coil for any signs of damage. Look for cracks, breaks, or burns. If you see any damage, then the coil may be bad.

If you are not sure whether or not the coil on your four wheeler is good, it is best to take it to a qualified mechanic for diagnosis.
