My radio just quit working one day I started my car (even with the key in the accessory position). The time is not being displayed (even with the key in the accessory position). The 7.5 amp radio fuse appears fine. I heard a buzz when I turned the key from the accessory position to start. Any ideas? Thanks!
Hi, Use an Ohmmeter to verify that the fuse is OK (pull the fuse out when you check it with the meter) or replace it with a known working same rated fuse. This is just to totally eliminate it as the problem so that you don’t waste time looking for something else if this was the problem You may have to remove the radio and use a Voltmeter to check that both 12V+ power supplies to the radio are available. One is from the radio fuse and one is from the ignition key accessory power feed circuit. Here’s a link to a video that shows how to remove the radio from the dashboard. Here’s a link that shows the radio harness wire colours and their function. If both power feeds are there then there is a problem in the radio itself which will have to be further investigated
