ELFCULB SAE Polarity Tester Instantaneous Detector for Current and Voltage Signals,with SAE Polarity Reverse Adapter for Battery Solar Panels SAE Connector Cable
[SAE Polarity Tester]The SAE polarity tester has a negative terminal on the round hole end and a positive terminal on the exposed end and can be used to differentiate between positive and negative voltage at the SAE harness port under test.
[SAE Polarity Reverse Adapter]Possibility to reverse the polarity of the SAE cable,different brands of solar panels may have different polarities.Please note the polarity before connecting.
[Test SAE Extension Cable] When the LED panel of the tester is illuminated, it indicates that there is voltage in the harness under test, and the voltage range of the harness under test is 3-36V.
[Wide Applications] The SAE polarity tester is suitable for distinguishing between positive and negative SAE connectors, testing for the presence of voltage in batteries, solar panels, SAE extension cables, and more.
[You Will Get]2*SAE polarity tester & 1*SAE Polarity Reverse Adapter.(Note：Before Using Please Make Sure the Positive and Negative Poles are Correctly Matched)
