Car Power Leakage Tester Parasitic Drain Diagnostic Tools

Car Parasitic Drain Tester connects a multimeter to the vehicle electrical system for diagnosing automotive hidden battery leakage. Car Parasitic Drain Tester Voltage Diagnostic Tool No Power Off Parasitic Drain Tester with 4mm Copper Plug Current Drain Test Tool.

Feature:
1. No Need to Worry about ECU Loss: This car leakage tester can test the car ECU while it is still powered up, so you don't have to worry about duplicating the test data due to ECU loss. It can also test automotive ECUs in standby, normal operating current or abnormal operating current electronic components.
2. Unique U-Shaped Terminal Spring Clip: The battery current detector has a unique U-shaped terminal spring clip design that allows direct connection to the terminals without removing the terminal wires, making it easier and faster to use.
3. More Durable and Efficient: The parasitic drain tester is equipped with an automotive drain tester, allowing the voltage at different locations on the vehicle to be measured during the drain test using standard test leads. Upgraded protection has also been achieved with fuses that are less likely to blow and low power consumption, thus increasing the overall durability and efficiency of use.
4. Fully Encapsulated High Current Battery Clip and Low Resistance Switch: This car leakage detector features a fully encapsulated high current battery clip and low resistance switch to ensure a long service life of over ten years. In addition, the tester has an on/off switch that can be turned off before connection for added safety. And it is also switch-treated to prevent surges during connection.
5. 4mm Solid Copper Plug: The battery leak detection tool is designed with a 4mm solid copper plug that can be plugged in continuously and used with a multimeter to read current values and measure voltages or currents. (as opposed to a multimeter). It is also equipped with a fully encapsulated high current clamp to ensure smoother operation of the product. A high current, low resistance switch is used, thus extending the life of the product.

Instruction:
1. Park and turn off the engine, open the hood, lock the door, and wait for the ECU to enter sleep.
2. Clamp the battery terminal (negative) with the spring clip, then use the fully wrapped battery clip to clamp the battery terminal clip (negative)/ground.
3. Flip the switch to the ON position (l/closed); Plug the 4mm banana plug (red) into the multimeter A/10/20A jack, and the 4mm banana plug (black) into the multimeter COM jack.Turn the dial of the multimeter to point to the A/10A/20A gear.
4. Loosen the battery terminal clip nut with M10 wrench, then disconnect the battery terminal clip from the battery terminal, which can be separated by cardboard or plastic sheet.
5. Turn the switch to OFF (O/Disconnect) to read the current value by multimeter.
6. If you need to change the range of the multimeter, you should turn the switch to ON (l/Closed), and then turn the multimeter dial. Select the appropriate range and re-plug to 4mm banana jack (red) [if necessary], and then turn the switch to OFF (ON/Disconnect).

Note:
1. Please turn off the engine and remove the key before testing the current leakage. Do not start the engine during the test to avoid burning the fuse.
2. Current leakage testing needs to simulate the usual state when the car is power-off, please be sure to shut the door, pull out the key (can be locked), so that the car computer into a sleep state.
3. Different car computers enter the hibernation state at different times, so please be patient when measuring to determine whether current leakage is generated.
4. The computer standby current varies from car to car, but the ideal value should be between 20 mA and 60 mA.
5. It is recommended to use a 10A fuse to replace the fuse of the line tester to avoid burning the multimeter.
