Do you have a problem with a specific device? Let me know and I may be able to tell you what Fuse/CB.

hi,

I seen some posting regarding similar problems on the following link:

http://www.us.playstation.com/support

Hopefully from this, it will lead you in the right direction.

Generally a "protect" mode would be triggered by a shorted output (speaker). I would suggest disconnection all of the speakers to see if the red light goes off.

Car Radio Wiring Diagrams and Car Stereo Wiring Diagrams

Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

bad head unit or look at your ground wire good luck

Hi,

Would you be aware if there is a pre-installed external amplifier attached to the old head unit?

If yes, the speakers are connected to the amp and not to the new CD player. There should be a pair of shielded wire with RCA male connectors that should go to the head unit and the other ends would be attached to the amplifier. Additionally, there is a trigger wire from the head unit that switches the power of the amplifier to ON aside from the power B+12 and GND.

If no, on the Ford pls verify that:
Green/Yellow - always on B+12VDC (positive battery terminal)
Yellow/Black - switchable +12 (ACC terminal of your IGN switch)
Black/Light Green - chassis ground
Orange/Blue - remote trigger on for power antenna or external amplifier(s)
Light Blue/Red - park light

Speakers
Orange/Light Green LF+
Light Blue/White LF-
White/Light Green RF+
Dark Green/Red RF -

Pink/Light Green LR+
Dark Blue/Orange LR-
Pink/Light Blue RR+
Light Brown/Red RR-
(R-right, L-left, F-front,RR-right rear)

On the head unit, often, the yellow normally goes to the always on B+12 such as the + terminal of the battery, the red to a switched B+ such as the ACC of the IGN switch and of course the black to the chassis/ground.

Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
