radio doesn't work. she got out of the car, the quit she got back in and the radio was dead. fuse 56 a 20 amp fuse is good, 6 a 5 amp fuse is good. 20 is a 10 amp fuse is dead with the fuse is good. could the door switch has somthing to do with it.
fuses that look bad are.
fuses that look good , can be , in FACT bad.
DMM, (flip to low ohms)
fuse reads 0 ohms, its good
fuse reads infinity its bad.
if fuse is good check for 12 at the radio power wire.
the radio must be ground do work, is it?
some radios have a separate ground wire (black) is it grounded?
post new radio make and model and can answer with 100% accuracy.
im a retire ET.
DC to daylight. experances.
good tells me that is Do not turn on the Radio yes, i never do in church. LOL.. if the radio is dead, (only) the fuse is blown.) there is a car radio fuse, in the fuse box and some radios have inline fuse an others have a fuse box in the back of the radio. no 2 radios work the same. but all need power and all have 1 or more fuses.
fuse, called dome fuse is blown, or radio fuse. fuses that look bad, are, fuses that look good, may be........... check fuses with an ohmmeter, fuses that look good can have very tiny cracks and are not good, only an ohmmeter works, on fuses with 100% accuracy. (a volt meter works in circuit even better !!!) Did you test the dome lamp to see if it really works? pull it , put across 12v battery ,does it glow? did you look at the radio. and see if it has its own inline fuse? did you hot wire the radio power wire to see if the radio even works at all? if you have DMM with voltmeter this is so very easy to trace. ask.
Easy way. With a test light connected to ground ( a test light is a tool that looks like a ice pick with a clear handle with a bulb inside, and a wire coming out the end with a clip on it) Connect the clip on the light to a metal ground under the dash and with the fuse panel where you can see it, touch the pointer to each side of the back of the fuses, with the key on. The light should lght on both sides of a good fuse. If a fuse lights the light on one side and not the other it's blown. For the radio to work three fuses all need to be good as theirs all the time power and key on power and lighting as the dash lights power. The cigar fuse many times provides the all the time power, But if it's blown the radio won't play. Pull one fuse at a time and look at them to see if the bar inside the fuse is good ( they can look good and be bad) back to the test light meathod, Look the fuses up in the owers manul and it'll tell you the location of the fuse but the radio fuse can be good and the radio strill not work as the cigar fuse has to be good too, There;s another fuse panel under the hood that has the main fuses near the battery, Again the test light is fastest and easiest as any fuse blown even though it's not the radio fuse can make the radio not play. Aftermarket radios can have inline fuses instlled by the radio installer and some have fuses right on the back of the radio.
If it's fuse 36, it should have a 15 amp fuse.
Do not confuse this fuse with the radio backup fuse, which is 7.5 amps but runs a lot of other circuits.
Put in a 15 amp fuse.
If it burns, the lighter may have a short.
