How to Read the Power Probe Fuse Voltage Drop Chart
The Power Probe Fuse Voltage Drop Chart is organized to help technicians quickly interpret voltage drop measurements across fuses. The chart typically categorizes fuses by type (e.g., standard, mini, maxi, or JCase) and lists them by their ampere ratings. Each row corresponds to a specific fuse, while columns represent varying circuit currents in milliamps (mA).
To read the chart:
Identify the fuse type and its amp rating from the circuit you are testing.
Locate the corresponding fuse row in the chart.
Determine the current flowing through the circuit using the Power Probe.
Match the current value to the appropriate column to find the expected voltage drop in millivolts (mV).
For example, if you are testing a 15A fuse and measure a circuit current of 150mA, the chart will provide the expected voltage drop for that specific condition. If the measured drop exceeds the chart’s value, it may indicate a faulty fuse or connection.
This method ensures accurate troubleshooting and helps identify electrical issues efficiently. By referencing the chart, technicians can quickly diagnose whether a fuse or circuit is operating within acceptable parameters.

Interpreting Voltage Drop Measurements for Accurate Diagnostics
Interpreting voltage drop measurements is crucial for accurate diagnostics in electrical systems. Using the Power Probe Fuse Voltage Drop Chart PDF, technicians can determine whether a fuse is functioning correctly or if it indicates a potential issue. To interpret the measurements, start by using the Power Probe to measure the voltage drop across the fuse. Note the fuse type, amp rating, and millivolt reading.
Refer to the chart to locate the measured voltage drop and cross-reference it with the fuse’s amp rating. This intersection provides the circuit’s current flow in milliamps, helping identify if the current is within the expected range. For example, a 15A fuse with an 8mV drop corresponds to approximately 167mA of current flow.
By analyzing these values, technicians can diagnose issues such as excessive current draw, faulty components, or parasitic drain. Always consult the wiring diagram to identify components protected by the fuse and isolate them to pinpoint faults. Accurate interpretation ensures efficient troubleshooting and repair of electrical systems.
Common Mistakes to Avoid When Using the Voltage Drop Chart
When using the Power Probe Fuse Voltage Drop Chart PDF, several common mistakes can lead to inaccurate diagnostics. One of the most frequent errors is failing to identify the correct fuse type before referencing the chart. Using the wrong chart for a specific fuse type, such as confusing mini fuses with standard ones, can result in misinterpretation of voltage drop measurements.
Another mistake is not ensuring the circuit is under load when measuring voltage drop. Measuring without load may not reveal the actual current flow, leading to incorrect conclusions. Additionally, some technicians might not account for parasitic draws or overlook the wiring diagram, causing them to misidentify the components protected by the fuse.
Lastly, not cross-referencing the measured voltage drop with the correct fuse amp rating can lead to false assumptions about the circuit’s condition. By avoiding these pitfalls and following the chart’s instructions meticulously, technicians can ensure precise and reliable diagnostics. Proper usage of the chart is essential for effective troubleshooting and repairs.
