How Do You Check The Resistance Of A Motorcycle Ignition Coil?
Motorcycle engines rely on three different ingredients to create combustion: air, fuel and spark. If any of these factors are missing, combustion will not occur, leaving your motorcycle inoperable. Missing spark is a common issue, preventing the compressed air and fuel in the cylinder from being ignited. While the cause of a no-spark situation can vary, from improper ignition timing to a dead battery, a primary culprit is a faulty ignition coil, whose role is to transmit an electrical current to the spark plug. Testing a coil is simple enough using an ohmmeter; however, this process will only identify broken or badly shorted windings within the coil. Disconnect the ignition coil from the motorcycle’s wiring harness and pull the spark plug caps from the spark plug. If possible, remove the entire coil from the motorcycle. Set your ohmmeter to the Rx1 range setting and place its positive lead (red) on the ignition coil’s primary wire. The primary wire is connected to the motorcycle’s brea
