| Now measure a **REFERENCE VOLTAGE**. Place the black lead on the negative battery terminal to take an initial voltage reading of the battery itself. This voltage should be close to 12.8 DC volts. Whatever your voltage reading, directly on the battery, will be called the **REFERENCE VOLTAGE**. | Now measure a **REFERENCE VOLTAGE**.

| - | When checking the voltage between the positive terminal of the battery and ANY GROUND POINT on the bike, you should have a voltage reading very close to the Reference Voltage (like 12.8v above). Every single ground point on the entire bike should measure within .3v of this reading. | + | When checking the voltage between the positive terminal of the battery and ANY GROUND POINT on the bike, you should have a voltage reading very close to the Reference Voltage (like 12.8v above). Every single ground point on the entire bike should measure within .3v of this reading (~2%). |
| So, if you take the black lead to the other end of the negative battery cable, on the powertrain ground or engine, it should measure near the Reference Voltage. If you take the black lead to the ground pin on the headlight connector, it should measure near the Reference Voltage. If you take the black lead to the ground pin in the taillight connector, it should measure near the Reference Voltage. If you take the black lead to the cylinder heads (next to the spark plugs), the meter should read near the Reference Voltage. | So, if you take the black lead to the other end of the negative battery cable, on the powertrain ground or engine, it should measure near the Reference Voltage.
