quick help question for radio wire...

[koUki20]

hi, i have a 89 240sx. i was just wondering, how come theres no power running through the 12v constant(red /w black stripe) on the radio harness? what would that mean? i checked the radio fuse and the audio fuse under the dash already. the 12v ignition wire seems to get power. any help would be great. thanks

It should be the room lamp fuse. I'm guessing you're getting no dome light either or clock? I had the same problem and i changed the "room lamp" fuse or something like that. it's the second or third from the top on the right side of the fuse box in the kick panel. It should be a 10 amp fuse.
