vehicle system Checklist
� Ensure the vehicle produces at least 12.6 VDC to reliably power the DMS, LectroCount register, and
control valve solenoids. Consult the manuals of each component for power consumption requirements.
� Clean any corrosion from the battery terminals and battery cable to guarantee a solid connection.
� Charge the battery in accordance with manufacturer’s specifications.
� Check the alternator capacity and ensure it can meet the demands of the DMS, LectroCount register,
printer, control valve solenoids, and all other electrical components.
� Inspect the electrical equipment on the vehicle, and ensure it is properly installed and operating correctly.
� Determine whether the the vehicle is grounded positively or negatively. Consult Liquid Controls if the vehicle
has a positive ground.
� Run the vehicle at a low idle with all accessories on (including the hose reel). Ensure that the voltage does
not drop below +9 VDC. If the voltage falls under +9 VDC, the LectroCount register will power down.
