How do you check coil on a ski doo?

To check the coil on a Ski-Doo, first, remove the engine cover and locate the ignition coil. Use a multimeter to measure the resistance across the primary and secondary terminals of the coil; refer to your specific model's service manual for the correct resistance values. If the readings are outside the specified range, the coil may be faulty and should be replaced. Additionally, inspect the wiring for any signs of damage or corrosion.
