Troubleshooting electrical circuits in bikes is a valuable skill for any e-bike owner. Common issues include a battery that won't charge, loose cables, or incorrectly connected wires. This can be due to age, owner error, or a blown fuse. To troubleshoot, you'll need to familiarise yourself with the bike's manual and arm yourself with a toolkit.

What You'll Learn
Checking the power switch
If the power switch is on but the controller still isn't working, check for any incorrectly connected, disconnected, or loose wiring. Most bike wiring is colour-coded, so a blue wire, for example, should match a blue port or outlet. If you see any improperly connected wires, you can reconnect them yourself. If you're not sure how the wires should be connected, refer to the bike's manual.
In addition to checking the power switch, it's also a good idea to verify the battery's secure connection and full charge. Check for loose cables or corrosion on the battery terminals, ensuring tight and clean connections. If the battery isn't charging, there could be several reasons. The fuse might be blown, the battery might be depleted from too-frequent charging, or the battery pack may be old or defective. Another possibility is that the battery's pins, which serve as the connector to the charging port, aren't properly placed, so the electric circuit isn't completed when the battery is plugged in. To troubleshoot this, try plugging the battery charger into the wall and see if any indicator lights turn on.

Checking for loose wiring
In addition to checking the wiring itself, it is also important to verify the battery's secure connection and full charge. Check for loose cables or corrosion on the battery terminals, ensuring tight and clean connections. The battery's pins, which serve as the connector to the charging port, should be properly placed so that the electric circuit is completed when the battery is plugged in. If the battery is not charging, try plugging the charger into the wall and seeing if any indicator lights turn on.
Loose wiring can also be caused by age or errors made by the owner or another person who worked on the bike. If you suspect that the wiring may have come loose due to age or handling, it is important to check all connections and ensure that they are secure. This includes soldered connections, which can become brittle and break over time.
Finally, if you are unable to identify or resolve the issue with loose wiring, it may be necessary to consult a professional or seek assistance from a qualified technician. They will have the knowledge and tools to properly diagnose and repair any issues with the electrical circuit in your bike.

Checking the battery charger
Troubleshooting electrical circuits in bikes can be done by checking the battery charger. Plug the charger into the wall and see if any indicator lights turn on. If the charger is working, the next step is to check the battery itself. Make sure the battery is securely connected and fully charged. Check for loose cables or corrosion on the battery terminals and ensure the connections are tight and clean. If the battery is not charging, the fuse may be blown, the battery may be depleted from too-frequent charging, or the battery pack may be old or defective. Another possibility is that the battery's pins, which connect to the charging port, are not properly placed, preventing the electric circuit from being completed when the battery is plugged in. Connections are weak points in electrical circuits, so it is important to ensure that all connections are secure. Soldering a wire to a connector or another wire and covering the join with a protective heat shrink tube can create a strong and waterproof connection. If soldering is not an option, a quality connector can be used instead, with the join covered by heat-shrinking.

Checking the battery's secure connection
Firstly, ensure that the battery is securely connected to the bike. Check for any loose cables or corrosion on the battery terminals. If you find any loose connections, make sure to tighten them. In case of corrosion, clean the terminals with a suitable solution to ensure a proper connection.
It is also important to verify that the battery is fully charged. A depleted battery can cause the electrical circuit to malfunction. If the battery is not fully charged, plug it into a power source and allow it to charge completely.
Additionally, pay attention to the battery's pins, which serve as the connector to the charging port. Ensure that these pins are properly placed and aligned correctly. Improper placement of the pins can prevent the completion of the electrical circuit, resulting in charging issues.
If you notice any incorrectly connected, disconnected, or loose wiring near the battery, take the time to reconnect them properly. Most bike wiring is colour-coded, making it easier to match the wires to the correct ports or outlets.
In some cases, you might need to solder a wire to a connector or another wire to ensure a strong and waterproof connection. If soldering is not an option, use a quality connector and crimp it securely to the wire before heat-shrinking it. This will help prevent connection issues and ensure the electrical circuit functions optimally.

Checking for corrosion on battery terminals
To check for corrosion, start by locating the battery terminals. These are the points where the battery connects to the bike's electrical system. Visually inspect the terminals for any signs of corrosion or buildup. Corrosion can appear as a white, green, or blue powdery substance, or as a sticky residue. If you notice any corrosion, it's important to clean it off to ensure proper electrical conductivity.
You can use a soft-bristled brush or a cotton swab dipped in a mild cleaning solution, such as isopropyl alcohol or contact cleaner, to gently remove the corrosion. Be careful not to apply too much pressure, as you don't want to damage the terminals. Once the corrosion is removed, dry the area thoroughly before reconnecting the battery.
It's also important to check for loose cables or connections during this process. Ensure that all cables are securely attached and that there is no movement or wiggling when you gently tug on them. Loose connections can lead to electrical issues and potential short circuits, so it's crucial to address them promptly.
By regularly checking for corrosion and loose connections, you can help maintain the integrity of your bike's electrical circuit and prevent potential issues before they become more serious problems.

Frequently asked questions
There are a few reasons why this could be happening. The fuse might be blown, the battery might be depleted from too-frequent charging, or the battery pack may be old or defective. The battery’s pins might not be properly placed, so the electric circuit isn’t completed when the battery’s plugged in. Try plugging the battery charger into the wall and see if any indicator lights turn on.
Connections are weak points in an electrical circuit. Twisting a wire to a connector or another wire and wrapping the join with electrical tape will not be sufficiently strong or waterproof, and will fail sooner or later. To fix this, solder a wire to a connector or another wire and cover the join with a protective heat shrink tube. If soldering isn’t an option, use a quality connector and crimp it securely to the wire before heat-shrinking it.
Start by checking the power switch. Switch it on if it’s not in the “on” position. Check for any incorrectly connected, disconnected, or loose wiring. If you see improperly connected wires, you can reconnect them yourself. Most bike wiring is colour-coded (so a blue wire matches a blue port or outlet). If the controller has a circuit breaker, reset the breaker.
Verify the battery's secure connection and full charge. Check for loose cables or corrosion on battery terminals, ensuring tight and clean connections.
