When a motorcycle ignition switch is not starting, it could be caused by a failed resistor. A small resistor, usually at 100 ohms, helps prevent hotwiring and other possible issues. Symptoms of a failed ignition resistor can include difficulty in starting up the vehicle, and further investigation may be needed to determine if this issue is present. However, if you’re caught in a tricky situation, knowing how to bypass a Kawasaki ignition switch can be valuable, providing a temporary solution until the faulty resistor can be replaced. The key to fixing this problem would involve replacing the defective part with a fully functioning one.

Can you explain the purpose of the resistor in your ignition switch?
This 100-ohm resistor is an effective anti-theft measure to protect bicycles from being hotwired. By installing it in series between the ignition switch and CDI (Capacitive Discharge Ignition), a lower voltage of approximately 9V is applied to the CDI. When this happens, the bike’s ECU can sense the reduced power level and allow power to reach its spark plugs.
Conversely, should someone attempt to bypass the security system by hotwiring your vehicle, then 12 volts will be applied, causing the ECU to block any power reaching its spark plugs, effectively turning it off until a correct key is used again? This simple yet essential device acts as extra protection for your bicycle against theft attempts.
Do all Kawasaki motorcycles come equipped with an ignition resistor?
Kawasaki does not necessarily fit an ignition resistor to all of its models. The fitting and requirements for this component depend on the model of the bike in question, as well as which country it was purchased from. Information regarding the presence or lack of an ignition resistor cannot be found in a motorcycle’s manual since manufacturers do not typically highlight if it is installed – such information is kept secure for security purposes.
What is the purpose of bypassing the ignition switch resistor?
The resistor is an essential component of an ignition switch. It provides the necessary resistance to protect the electrical system from voltage spikes and helps maintain regular operation and stability. When this resistor fails, it can result in malfunctioning or complete failure of the ignition switch, preventing proper starting of the bike. This can be very frustrating for any rider as all other lights and instruments may appear to be functioning normally despite being unable to start their vehicle.
How to bypass the ignition switch resistor?
This job requires some electrical knowledge and the right tools, so it is best to refer the bike to a qualified mechanic if there is any uncertainty in attempting it. Otherwise, bypassing the resistor should be able to be completed as a DIY project.
Here are the parts and tools you will need.
- The 100-ohm, 1/2-watt resistor is essential for completing this project.
- A soldering iron will ensure a strong bond between components and wires.
- Soldiers must be melted to create the electrical connections needed in this project.
- Wire of the same gauge as the current switch wire should be used to ensure proper fitment into existing configurations and spaces.
- Heat shrink should be applied over all exposed wiring for safety and to guarantee that it remains secure throughout its lifetime.
- A heat gun may prove necessary. However, it is possible that a hairdryer could produce adequate results in some cases.
Resistor bypass process
The ignition switch must be removed to access the original resistor on its bottom. Refer to the bike’s manual for instructions on properly doing this. For a bypass of the resistor, it is recommended that any cutting and inserting should take place at the ignition switch wiring side rather than through interference with the main loom. Replacing the existing resistor may be an option if sufficient technical expertise is available; however, bypassing it may be simpler and more convenient.

How to bypass the ignition resistor like a pro
- Unscrew the ignition switch from its mounting point to access the resistor.
- Carefully cut into the wiring side of the ignition switch, avoiding any potential damage to other wires in the loom.
- Connect a suitable resistor across the two ends of the cut wire – make sure you use one with a low resistance rating!
- Use insulation tape or heat shrink tubing for extra security and reassemble your bike’s components according to instructions in your manual after checking that everything is connected correctly and securely fastened down.
- Test all functions before taking it out on a ride – safety first!

Final Thoughts on Bypass a Kawasaki Ignition Switch
Many Kawasaki ignition switches are fitted with a 100-ohm resistor. If the usual fixes for starting problems fail to do the trick, this component may be at fault. Awareness of its presence and potential malfunctions can help avert future frustrations when dealing with such issues. However, knowing how to bypass a Kawasaki ignition switch can be a temporary fix until the faulty resistor is replaced correctly.

FAQs About Kawasaki Ignition Switch
What leads to the malfunctioning of an ignition switch?
When an ignition switch is faulty, one might encounter difficulties starting the engine, maintaining its operation, or activating other systems upon turning the key. Additionally, turning the key might become challenging. So, what typically results in the breakdown of this switch? Predominantly, it’s the wear and tear from countless key rotations and the weight of bulky keychains.
Is there a method to circumvent the ignition switch?
To do so, one would connect the battery’s positive terminal to the ignition coil’s positive end. It’s also essential to pinpoint the starter solenoid and link it to the battery’s positive terminal. Following that, detach the wire of the ignition switch from the solenoid. Finally, bridge the solenoid’s terminal to the point where the ignition switch was previously connected.
How can someone recalibrate or initialize a new ignition cylinder using a key?
To achieve this:
Turn the key to the ON position and let it remain there for precisely 10 minutes and 30 seconds.
Switch the key to the OFF position and wait for around 10 seconds.
Repeat this process: ON for 10 minutes and 30 seconds, then OFF for approximately 10 seconds.
After the third cycle, turn it ON and proceed to ignite the engine.
Where can one locate the key code for a Kawasaki?
The key code is engraved on the ignition switch for most Kawasaki models. To observe this code, one would need to extract the ignition switch.
