Check the battery's voltage with a volt or multimeter
If your Harley Electra Glide motorcycle is having starting issues, it could be due to a weak or dead battery. Before attempting to jump-start your Harley, it is important to check the battery's voltage to confirm that it is, in fact, drained. This can be done using a volt or multimeter. Here is a step-by-step guide to checking the battery voltage of your Harley Electra Glide:
First, locate the battery. On a Harley motorcycle, the battery is usually placed inside the frame under a battery cover. Remove the seat to access the battery.
Next, take your volt or multimeter and identify its components. A multimeter has two probes: a red probe and a black probe. The red probe is connected to the multimeter's positive terminal, while the black probe is connected to the negative terminal.
Now, connect the probes to the corresponding terminals on the battery. The red probe should be attached to the positive terminal of the battery, and the black probe to the negative terminal. Ensure that the connections are secure and that the probes are not touching any other parts of the motorcycle.
Once the probes are connected, adjust the settings on the multimeter. Set the multimeter to DC voltage mode by turning the dial or knob to the symbol that denotes direct current (DC). This is usually indicated by a 'V' with a straight line and, in some cases, three dashes (⎓) followed by a range of numbers. Set the range higher than the expected battery voltage, which is typically 12V for a Harley motorcycle.
After setting the correct mode and range, observe the voltage reading on the multimeter's display. A typical healthy battery will show a voltage reading at or slightly above the rated voltage. If the voltage is slightly below the rated voltage, the battery may be weak and need recharging. A significantly lower voltage indicates a drained or dead battery.
Note that it is important to keep the negative terminal of the battery away from metal, chrome, and painted motorcycle parts to avoid damage and staining. Additionally, ensure that the multimeter probes are connected correctly and securely to obtain an accurate reading.
By following these steps, you can accurately check the battery voltage of your Harley Electra Glide using a volt or multimeter. This will help you determine if the battery needs to be recharged or jump-started. Remember to perform regular maintenance checks on your motorcycle battery to reduce the risk of starting issues.

Keep the negative terminal away from metal, chrome, and painted parts
When jump-starting a Harley Electra Glide, it is crucial to pay attention to the battery's negative terminal. The negative terminal of a battery is typically indicated by a minus sign or the colour black. Keeping this terminal away from metal, chrome, and painted parts of the motorcycle is essential to prevent damage and staining.
Harley-Davidson motorcycles are equipped with a 12V battery. If the battery becomes drained, you may need to jump-start the motorcycle using another motorcycle or a donor battery. However, it is important to remember that Harley-Davidson does not recommend jump-starting a motorcycle as it can potentially cause permanent damage to the battery and electrical systems.
When jump-starting, always ensure that the negative terminal of the battery is handled with care. Keep it away from any metal, chrome, or painted surfaces on the motorcycle. Even a brief contact between the negative terminal and these parts can lead to undesirable consequences. Touching the negative terminal to metal can cause an explosion, resulting in severe injuries or even death. Therefore, it is crucial to maintain a safe distance between the negative terminal and any metal, chrome, or painted components.
To ensure safety, follow these guidelines: after connecting the jumper cable to the donor battery's negative terminal, be cautious to prevent the other end of the cable from coming into contact with the negative terminal of the drained battery. Always keep flammable objects away from the work area when jump-starting to mitigate the risk of accidents.
By adhering to these precautions and keeping the negative terminal away from metal, chrome, and painted parts, you can safely and effectively jump-start your Harley Electra Glide while minimising the risk of damage or injury.

Connect the donor battery to the drained battery
Jump-starting a Harley Davidson motorcycle should only be done in emergencies as it can be dangerous and cause permanent damage to the battery and electrical systems. If your Harley Electra Glide won't start, first check the battery's voltage. If it is below 12V, the battery is drained and must be recharged.
If you are on a motorcycle tour and no mechanic shops are located nearby, you can try to jump-start your Harley Electra Glide. You will need a donor battery that can generate 12V, jumper cables, and wrenches to remove the seats to access the batteries. Ensure that the donor battery is not generating a higher voltage, as this can cause permanent damage to the drained battery and the motorcycle's electrical systems.
Turn off both motorcycles and all electrical equipment. Remove the seats to access both batteries. Keep the negative terminal/cable of the battery away from the metal, chrome, and painted motorcycle parts to avoid damage and staining. Ensure that the other end of the cable does not touch or come close to the negative terminal of the drained battery, as this could cause an explosion resulting in severe injuries or even death. Keep any flammable objects away from the work area.
Use a jumper cable to connect the positive terminal of the drained battery with the positive terminal of the donor battery. Using another jumper cable, connect one end to the negative terminal of the donor battery. These connections will transfer power from the donor battery to the drained battery.
