Last Friday, I ordered help-held Autel AutoLink AL539B OBD2 code reader from obding for all of us$150 with CCA Test Line for AL539B (they suggested me buying the test line). AL539B and CCA Test line came within my door three days later via DHL. My first impression was “Yeah, it becomes an original Autel .”

Certainly, the handy gadget AL539B code reader can perform fairly accurate basic diagnostic and vehicle identification which were inside my expectation. I have once seen it done my co-work’s car and also this time I got enable you to give it a try by myself. It just worked 100%. But I used to be baffled by the application of the CCA Test line. I called anyone manual. According to the manual, AL 539B can provide quick and accurate load-free testing for some sort of 12V batteries, including AGM, standard and maintenance-fee batteries with the help of CCA line.


Initially when i first connected CCA line using the AL539B tester. Then go out the power of circuit while removed the wire nuts in the black hot wires and also the white neutral wires to part ways them apart. Turn the electricity on and plugged CCA Line in to the circuit card. Circuit voltage, circuit resistance and circuit current can be clearly shown on screen by using the bright color coded LED. While using Autel AutoLink AL 539B code reader, I don’t need to buy other electrical tester anymore. It truly is truly worth a stab.
