E-ONE VEHICLES ARE DESIGNED WITH ELECTRICAL CIRCUIT PROTECTION (E.G.

FUSES), TO PROVIDE OVERCURRENT PROTECTION DURING SHORT-CIRCUIT CONDITIONS OR MALFUNCTION OF COMPONENTS. FUSES ARE SOMETIMES SHARED AMONGST DIFFERENT CIRCUITS. FOR EXAMPLE, THE CIRCUITS FOR THE PUMP PRIMER MOTOR AND CHASSIS POWER SHARE A COMMON 300AMP FUSE. IF EITHER OF THESE CIRCUITS EXPERIENCES AN ELECTRICAL OVERLOAD, THE FUSE WILL ACT AS DESIGNED TO PROTECT THE USERS AND THE VEHICLE FROM FURTHER DAMAGE. AS SUCH, AN OVERCURRENT CONDITION IN THE PUMP PRIMER CIRCUIT WILL ALSO DISCONNECT MAIN POWER FROM THE CAB AND CHASSIS AND CAUSE THE ENGINE TO SHUT DOWN.

3 bulletinsThis tool is designed to compare Diamond Logic feature data across multiple vehicle configuration files.
Read full bulletin
It allows users to quickly load files either manually or directly from the Diamond Logic Builder Vehicles folder using VIN-based selection. As files are added or removed, the comparison runs automatically with no manual action required. The program presents results in an interactive table that shows feature codes, descriptions, access levels, and whether each feature is present in each selected file. Built-in search, filtering, and sorting make it easy to locate specific features or focus only on differences between files. Column visibility can be customized to show or hide descriptions and access information as needed. Users can remove files individually or clear all files at once, with results updating instantly. The tool also includes reporting and export options that reflect exactly what is visible on screen, allowing results to be printed, copied, saved as text, or exported to CSV for use in Excel or other spreadsheet tools. Overall, the program streamlines the process of comparing vehicle feature configurations, helping users quickly identify differences, validate setups, and document results without manual comparison or external tools.
