I have taken out a Kenwood Tape Player and now I am putting in a new CD Player. After I have taken the tape player out I seem to have no power for the CD Player I have wired this right because I have done this before. I have checked the fuses but they seem ok. Is there something else that I can check. I even wired the old one back in and now it doesn't work either.

 

Make sure these wires are right and that it is grounded to metal.

Orange: 12v (const.)
Yellow: 12v (switched, ignition)

Double check those fuses too!

Let me know how it goes,
Matt
