I've been trying to troubleshoot this recent problem I've been having with my TB. My AppRadio won't turn on. Manually checked for power on the source power, have 12V there so that's good. I don't have power going to the key on wire however. I'm trying to troubleshoot but don't know how to tell if the module has gone bad (it's note even 6 months old) or if there is something in front of the module has gone bad. This problem popped up yesterday after I finished getting the dash back together after running a 12V wire from the battery to the top of the dash. I had to get access behind the radio so I unplugged the radio from the back of the radio (didn't even touch the module) and finished routing that other cabling. I did go back there briefly to ground to the substructure but I still had 4" or so of space before moving anything. Any help/suggestions would be nice.
