Comet Lighter Repair
The lighter socket was not working so I replaced the burned out sulfur disc fuse with a 15 amp inline fuse from Radio Shack- now I can charge my phone
   

The ligher socket assembly removed from the dash
This screw-on cylinder is an old sulfur disc fuse- it was not conducitng current
I replaced the disc fuse with an inline mini-blade fuse Radio Shack # 270-1237
Most cigarette sockets are rated 15-20 amps so I used a 15 amp mini-blade fuse
