If a fuse has blown, it’s essential to find out the rationale for the failure earlier than putting in a brand new fuse.
Ignition and Kill Swap Verification
Lastly, study the ignition swap and the kill swap. Ensure the ignition swap is within the “On” place. Many have been caught by forgetting to show the ignition on. Make sure the kill swap is just not engaged (typically a crimson swap on the handlebars). If the kill swap is activated, it prevents the engine from beginning.
Deeper Dive: Superior Diagnostics
Starter Relay Examination
If these preliminary checks don’t clear up the difficulty, it’s time to probe deeper. Right here, we’ll examine different potential causes and easy methods to diagnose them.
The starter relay is the following suspect. This small electrical part is chargeable for sending energy from the battery to the starter motor. The “click on” you hear is commonly the relay’s try and do its job, however one thing is stopping it from finishing the duty.
To check the relay, find it (seek the advice of your Harley’s service handbook for the exact location). You possibly can typically take a look at the relay with a multimeter. The method sometimes includes testing for voltage throughout the relay’s terminals when the ignition is turned on. In case you’re not snug with this, don’t hesitate to seek the advice of your service handbook. It’s also possible to attempt swapping the relay with one other comparable relay (e.g., out of your horn). If the bike begins after a swap, the outdated relay was certainly the difficulty.
Starter Motor Inspection
Subsequent, study the starter motor itself. This highly effective motor is designed to show the engine, and it might probably fail for quite a lot of causes.
Potential starter motor issues can embrace worn brushes, a defective solenoid (which engages the starter gear with the flywheel), or inside brief circuits. To check the starter motor, you may quickly bypass the starter relay. *Security word: Disconnect the unfavorable battery cable earlier than doing this*. *CAUTION: This isn’t the identical as eradicating the unfavorable terminal from the battery. It is merely the cable. This ensures you don’t brief the starter motor. It is not going to be coated by your insurance coverage.* Use a jumper wire to attach the constructive terminal of the battery on to the starter motor’s energy terminal. If the starter motor cranks the engine, the motor itself is probably going operational. If the motor doesn’t work, it’ll must be changed.
Solenoid Evaluation
The starter solenoid works with the starter motor. It’s one other perpetrator to research. It will get energy from the starter relay. The solenoid mechanically engages the starter gear with the engine’s flywheel whereas supplying energy to show it over. Issues can embrace defective wiring, or the solenoid itself. Testing it typically follows an analogous course of to testing the starter motor, as beforehand mentioned. Changing the solenoid is commonly mandatory when it malfunctions.
Wiring and Grounding Evaluation
Wiring and grounding points will also be the trigger. A poor floor connection can forestall ample present from reaching the starter motor, leading to a click on however no crank. Examine your complete wiring harness for any harm, equivalent to chafing or corrosion. Establish the grounding factors in your Harley. These are the factors the place {the electrical} system connects to the body of the motorbike, finishing the circuit.
Clear and tighten all floor connections. Use a wire brush to take away any corrosion, and make sure the connections are safe. Testing the connections along with your multimeter, as beforehand mentioned, will allow you to establish issues.
Different Doable Causes: Much less Frequent Points
ECM Issues
Whereas the objects talked about beforehand are extra probably, different potentialities may additionally trigger your Harley to make a click on.
The Engine Management Module (ECM) can generally be the supply of the issue. The ECM is chargeable for managing the engine’s features. If the ECM is defective, it could not ship the proper indicators to the starter relay. Nonetheless, ECM points could be complicated, and it is typically finest to hunt skilled help with ECM diagnostics.
Crank Place Sensor (CPS) Points
Crank place sensors (CPS) will also be the issue. The CPS, or crank place sensor, is one other part that may forestall your engine from beginning whether it is faulty. The CPS is designed to detect the crankshaft’s place, so it might probably coordinate gasoline injection and ignition timing. If the CPS fails, the engine will not have the ability to begin.
Inside Engine Issues
Lastly, inside engine issues, equivalent to a seized engine or a damaged starter clutch, could possibly be accountable. If you’re experiencing this, have knowledgeable diagnose the bike.
Security First: Defending Your self and Your Harley
Battery Security
Engaged on any electrical system requires warning. All the time prioritize security, regardless of how minor the duty appears.
When working with the battery, at all times put on eye safety and keep away from contact with acid. When disconnecting the battery, at all times take away the unfavorable (black) cable first, and reconnect it final. This minimizes the danger of a brief circuit.
