I mistakenly while I was fixing the charger house in the car, I connected Anker power drive+2 reversely then I recognized that the connection is wrong . I have corrected it but after that Anker power drive+2 did not work. Any one can tell me how can I repair it, Please
Update (06/12/2019) Hi Jafeff, Thank you for reply and help I am attaching here a pictures of the charger and hope if anyone can help.
Hi @mnaqil , reversing the polarity of the supply would have possibly damaged (destroyed) some components on the circuit board Post some close up pictures of the circuit board from the device back here and maybe someone can spot the problem. If not you’ll need to trace the circuit from the input through the components using an Ohmmeter etc to determine which component (or components) are faulty. Hopefully it will be something obvious.
