What controls spark on a motorcycle?

What controls spark on a motorcycle?

A battery or magneto to supply low voltage current for the spark. Mechanical contact points to control the point of ignition. A rotating cam to operate the contact points. A condenser to reduce arcing across the contact point surfaces.

Will a bad stator cause no spark on a motorcycle?

If the stator is bad, the bike won’t run at all. The stator generates energy for spark. Assuming the air cleaner is clean and other general maintenance has been performed, if the bike won’t kick start but runs as you state, the problem is probably either the spark plug and/or fuel delivery.

How many ohms should a stator have?

You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.

How do I test a CDI with a multimeter?

The connector comes directly from the stator and goes straight to the ignition box or CDI box of your motorbike. After finding the connector, set your multimeter at a resistance of 2k Ohms. Then, take a measurement of the resistance between the white wire to the blue wire.

How do you troubleshoot a motorcycle charging system?

Diagnosing Battery Problems: Quick Check

1. Check that all connections are tight and not corroded.
2. Use a digital multimeter or battery tester to check the battery’s voltage: Standing voltage for a healthy battery should be around 12.5 – 13 volts. Running voltage while charging should be between 13 – 15.5 volts.

How do I test my bike alternator?

Another way to check if the alternator is working properly is to simply touch the + and – pins of the tester to the + and – terminals of the battery while the bike is running. Multimeter should be set to DC voltage with the decimal point positioned as so: 00.0.

What causes a motorcycle stator to go bad?

To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.
