What is the method to check the condition of an ignition coil?
1 Answers
Check the condition of an ignition coil by: 1. Using the substitution method—replace one ignition coil with a known good one; if the fault disappears, it indicates the original coil is faulty. 2. Measuring the primary and secondary winding resistances with a multimeter; a high resistance reading suggests an open circuit fault in the winding. The steps to replace an ignition coil are: 1. Open the ignition coil cover on top of the engine. 2. Remove the ignition coil fixing screws. 3. Disconnect the ignition coil power plug. 4. Remove the ignition coil. 5. Install the new ignition coil and tighten the screws. 6. Reconnect the power plug and replace the top cover.
