FAQs
When the unit's test switch is turned ON, neither of the LEDs flashes — or the red LED flashes seven times.
If the LEDs don't flash, the batteries are dead. If the red LED flashes seven times, the batteries are low. In either case, the batteries should be replaced. Remove the back battery cover and replace the three AAA batteries. Replace cover and confirm that the Carter CV1000 is working properly (as stated in Steps 5 & 6 of the instructions).
The Carter CV1000 only indicates a failed condition.
Review and inspect the 15-foot attachment cable and adaptor harness connections.
Make sure the screw terminals have been securely hand tightened. Make sure the adaptor harness has been properly inserted into its respective 15-foot attachment connector and fuel pump harness.
The red LED flashes, but the buzzer does not beep.
This indicates that no fuel pump voltage was present. Make sure that once the Carter CV1000 test switch has been turned ON, the vehicle ignition switch is turned to the RUN position within 3 seconds.
The unit has gone into power-saving mode.
If the Carter CV1000 test switch has been left in the ON position for more than one minute, it will go into a power-saving mode. To reset the Carter CV1000, turn the test switch to the OFF position, then proceed with the normal test process.
How does the tool determine and indicate a fuel pump malfunction?
The CV1000 is actually verifying that the fuel pump electrical circuit is delivering the proper amount of voltage to the pump. If the circuit is not operational, the pump should be considered in good condition. If the circuit is operating properly, the source of the fuel delivery problem may be the fuel pump, a plugged in-line filter, faulty pressure regulator, etc. Further diagnosis of the fuel system will be required to determine the exact cause. Once the tool is attached to vehicle's fuel pump harness, it will flash a "Ready" signal (Red and Green lights flashing one time). Within 3 seconds of this signal, the user must turn the vehicle's ignition switch to the RUN position. If the tool's Green light flashes and the buzzer beeps, the electrical circuit is functioning properly (fuel pump may be at fault — further diagnosis is required). If the Red light flashes and the buzzer beeps, the electrical circuit itself is not functioning properly (fuel pump OK).
Is the Carter tool safe to use on any vehicle?
Could it damage vehicle electronics?
The Carter CV1000 comes with three of the most common manufacturer-specific harness adaptors for use with Ford, GM and Chrysler applications. Additional connectors for other applications will be available. The CV1000 is a 100% passive tool that monitors available voltage only. It does not produce or transmit voltage. The unit will not damage vehicle electrical systems.
Can the tool cause electrical system damage or produce inaccurate readings if not used correctly?
The CV1000 is equipped with an advanced semi-conductor that always provides a non-polar input. This ensures the tool will work correctly even in cases when its terminals are accidentally reversed. Because the tool is a fully passive device, it will not affect the vehicle electrical system.
Will we need two technicians to use the tool?
The CV1000 is designed for use by only one technician. The 15-foot cable allows the user to sit in the driver's seat with the activated tool in hand.
