Why is my motorcycle not getting a spark?
If you are having a no-spark problem, a good place to start after ruling out shorts, grounds, switches and spark plugs, is the ignition coil, spark plug caps and wires. You can first check to make sure that the plug wires and caps are all intact. A breakdown in the insulation can cause arcing in the plug wire.
What happens if there is no spark in the ignition coil?
Hence, without this high voltage, there is no spark and, consequently, internal combustion cannot take place within the engine. Simply put, the bottom line is without spark the engine doesn’t run.
How to troubleshoot a Yamaha yfm200 with no spark?
Place the black probe in the white and red terminal. The multimeter should display a 196 ohm reading, indicating that the ignition pickup coil is in operating condition. Replace the pickup coil in the left crankcase cover if the resistance reading is not 196 ohms.
What happens when you replace the coil wire on an engine?
You can replace the secondary coil wire on an engine that uses one with an equal length of vacuum hose and the engine will start and run. The powerful spark will travel down the hollow hose to the distributor cap, but the engine will stall under any load because of the weakened spark.
Why does my car have no spark when I start it?
As a result, This occurs after the ignition coil or module gets too hot. Furthermore, it could correct itself after the engine module cools. In some cases, a bad ignition coil will result in the vehicle not starting it all. A Bad Rotor Or Distributor Cap (cracks or carbon tracks that are allowing the spark to short to ground).
What happens when there is no spark from the ignition coil?
1 Power. Two positions of the ignition switch provide power to the positive primary post of the ignition coil. 2 Signal. With no external signal to the coil negative primary post, voltage would travel through the ignition coil windings without inducing any secondary spark. 3 Flow. 4 Open Circuits.
