The case ground is the same for the entire instrument cluster so if the instruments work so does the ground. Yes, then it is a faulty ground (I dought this, if instruments work).īy the way the light socket must be plugged into the hole to complete the circuit. If no, and no power on both sides, faulty light switch.Ģ. Do you have power to both sides of the fuse? If you look over the dash at the support bracket you should see a ground wire attached close to the emergency flasher.ġ. The black wire on the 12 pin connector is the ground and it is attached to the steering wheel support bracket. Grounding is provided through the metal of the Instrument panel.ĥ.
Fuse block to the 12 pin connector for the Instrument Panel.Ĥ. Light Switch (Blue/Red stripe) to the fuse block.Ģ. Instrument Panel lights power flows as follows:ġ.

Over the years the ground connection has been left off or lost, leaving the gauge illumination grounded only when it's installed and then only by the contact with the metal portion of the dash. I'm assuming the ground wire between the back of the instrumentaion cluster is present and OK. Other comments suggesting the constant voltage regulator (CVR) or in error the CVR cuts down the 12+ volts other vehicle systems operate from to a constant 5V for instrumentation. No power to either side of the fuse would indicate either a bad connection between the connector to the light switch and switch itself or a bad switch. No power in this wire would require checking either side of the fuse. Power in this wire would indicate a problem in the connector to the gauge cluster. Power in this wire comes from your headlamp switch via a fuse.

I thought it also lit the shifter selector, but I may be mistaken as I don't have any manuals available at this time.

Radio Install Kit and Wire Harness for Ford: 04-06 Expedition (No Nav). It lights the dash lamps as well as the radio. Fits Ford Mustang 2007-2008 Double DIN Stereo Harness Radio Install Dash Kit. Sorry for the confusion, the power for dash lamps is carried through the Light blue with red stripe (hence my LtBl/Rd) wire.
