What are the symptoms of a bad CDI box?

Symptoms could include misfiring, dead cylinders, backfiring, bizarre tach behavior, and countless other things related to how your engine’s running. The problem may get worse as the bike warms up. It might not even hold low revs at all.

How do I test my Kawasaki CDI?

First measure the resistance between the primary wire that comes from the CDI box and the ground or ground wire. The resistance should measure around . 5 to 1.5 Ohms. If that checks out, you can then measure the resistance between the secondary wire (plug wire), w hich should measure in the thousands.

What would cause no spark from coil?

Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.

What gives the ignition coil power?

The battery provides low voltage electricity to the ignition coil. That moves other distributor parts that cause the ignition coil to pulse, and sends the electricity down each spark plug wire in order. The power travels down the spark plug wires to the spark plugs and causes sparks.

Does a coil have constant power?

Re: Coil has constant power Yes, the coil is always connected to the battery. It’s no more of a problem for the wires IN the coil than it is for the wire ON THE WAY to the coil, as long as there is no current flow.

How do I know if my ignition coil has power?

Check for power using a test light.

If this wire has no power, then your ignition coil is not receiving current.
If this wire has power, then the wiring from the ignition switch to the coil is working properly and you can move on.

Can I drive with a bad ignition coil?

It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine.

Should I replace ignition coils with spark plugs?

Worn spark plugs can cause unnecessary load on the coils and there is often some overlap in the labor required to replace both components. If your ignition coils failed as a result of worn-out spark plugs, it is wise to replace both components at the same time.

Can a bad coil cause transmission problems?

It’s possible that a bad coil in itself could cause the car to jerk when shifting into gear, but any misfire bad enough to cause this kind of jerking will probably manifest as a noticeable engine shaking under other conditions as well.

What are the first signs of a transmission going bad?

10 Symptoms of a Bad Transmission

Lack of Response. Hesitation, or outright refusal, to shift into the proper gear is a telltale sign of transmission trouble.
Odd Sounds.
Leaking Fluid.
Grinding, Jerking, or Shaking.
Burning Smell.
Won’t Go into Gear.
Service Engine Soon.
Noisy Transmission in Neutral.

Should you replace all ignition coils at the same time?

You do not have to change all the ignition coils at the same time. It’s more about strategy. You will probably save time, money and frustration in the long run if you do.

How much does it cost to replace ignition coil?

The average cost for ignition coil replacement is between $247 and $261. Labor costs are estimated between $51 and $64 while parts are priced at $197. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
