6-24V DC Car Circuit Tester with Overload Protection, Detachable, 4m Cable - Short Circuit Locator, Continuity Tester for Automotive Electrical Systems

Item Type: Circuit TesterMaterial: Plastic, MetalOperation Voltage: 6-24V DCCable Length: Approx. 4m/4.4ydOverload Protection: 8A (When the current exceeds 8A, this item will disconnect the current automatically.)Applications:1. Test for continuity2. Test for polarity of a voltage3. Check switches, relays and the on-off of diodes, fuses and circuits 4. Test for polarity of electric cables and plugs5. Track and locate short circuits6. Test for bad ground contactsOperation Instruction:Unroll the unit's cableClamp the red clip to the positive terminal of the vehicle's batteryClamp the black clip to the negative terminal of the vehicle's battery Tips:1. An alarm sound made by the item indicates that the circuit breaker trips off.2. After the circuit breaker trips, it will reset automatically within 3 to 5 seconds.3. After an alarm sound, if this item is still connected with the testing object and you keep pressing down the power switch, the circuit breaker will repeat the process of trip and reset automatically.Do's and Don'ts:1. Do not use the item around gas, vapor, or dust. When the power switch is pressed (or rocked), battery current is conducted directly to the tip which may cause sparks when contacting ground or certain2. The unit is not to be used with 110/220V house current, it is only use for DC 6~24V systems.3. Do not use on AC voltage.4. After you finishing checking vehicle, correctly restored all the connection-s which you disconnected.5. Always follow the instructions and procedures indicated in the vehicle's service manual before attempting to disconnect any part or subsystem of the electrical circuit.6. Never touch any dangerous part of the vehicle with your hand for safety. Don't touch any live conductor with hand or skin.7. Don't use it if it is damaged.8. Some components of vehicle work on low
