Seeing as though my issue is with my car’s radio, i thought this the best place to post my question(s). To cut a long story short, i had a parasitic drain in my car that was traced back to my car’s radio. Now that i know what caused my battery to die, i would like to get a new car radio. But, before i move ahead, i would like to know how i would know if it was the circuit that caused the issue or was it the radio itself? There are no other electrical issues with me car. Therefore, how would i test to see if there is a ground issue on the circuit that my radio is on? I have attached a photo of the radio model if it helps.
Your help is appreciated. Thanks

Any ground wires that go to the radio will be grounded all the time. If their was a power wire grounding out it would blow a fuse. I assume you want to know how to prove that it is the radio itself and not a wiring issue. Electronic Module failure is a hard thing to prove. You basically have to gather enough evidence that points to that module and make an educated diagnosis.
Thanks for your reply. Yeah, i just want to know if it really is the radio and nothing in the circuit. I can get a new head unit from the scrap yard for $100; but if it is something in the circuit, it won’t matter. Though, i suppose that may be the only way to answer my question. No fuse has blown. Before the battery got killed, the sound from the radio was acting up.
