DY18 12/24V DC 10A Automotive Circuit Tester, Overload Protection, with Power Probe and 4m Cable

Features:

1. This power probe can help you quickly identify the positive and negative polarity of cables and plugs. The red light indicates positive polarity and the green light indicates negative polarity.
2. You can also test for continuity using the auxiliary ground wire. Check continuity of switches, relays, diodes, fuses, spark plugs and circuits.
3. Accelerated short circuit, when the fuse blows, it may be caused by a short circuit or a sudden increase in component load. The circuit tester can help you locate the problem cable and find the break point.
4. For some components that require large current to flow through the negative terminal, the short circuit protection circuit tester can immediately test the poor ground contact and jumper cable.
5.The test pen has an overload protection function.If the current or load is too high during power delivery, the test pen will automatically disconnect to protect the battery and emit an audible warning.
6.The insulating material used in the electrical tester has passed the mandatory national safety certification CCC, which is safe and reliable.It is widely applicable to all 6-24VDC vehicle electrical systems.
7.With a 4-meter long cable, you can easily conduct tests.This device is the best electrical tester for reducing diagnostic time on automotive electrical systems.

6. Testing for poor ground connections
Dos and Don'ts:
1. Do not use the item near explosive gases, vapors, or dust.When the power switch is pressed (or flipped), battery current is conducted directly to the tip, which may cause sparks upon contact with ground or certain
2.The unit must not be used with 110/220V household current; it is only for use with 6-24V DC systems.
3.Do not use with AC voltage.
4.After completing the vehicle check, properly reconnect all connections you have disconnected.
5.Always follow the instructions and procedures in the vehicle's service manual before attempting to disconnect any part or subsystem of the electrical circuit.
6.Never touch any dangerous parts of the vehicle with your hand for safety reasons.Do not touch any live conductors with your hand or skin.
7.Do not use if it is damaged.
8.Some vehicle components operate at low voltage and cannot withstand the voltage applied by this item.To avoid damaging these components, do not use this item to apply voltage directly or indirectly.
9.Before driving, always ensure the vehicle is safe and reliable.
10.Do not use this item while driving.
