No power to memrey wire for stero - 1998 Ford Expedition

It probably has two power wires going to it. One is just for the illumination. Make sure you get it right. Usually a yellow wire is the power and an orange wire is for the lights but they vary.

I’m happy to assist further over the phone at https://www.6ya.com/expert/kim_3202917d7c587455

probably picked up the wrong power wire for the unit and the power is diverted to the ignition circuit.. have the installation checked by professional audio fitters.

the dash lights dont get fed from the stereo , you may have dislodged the wiring connector from the rear of the dash , give them all a push back on , don't worry about the spare wires , they will be for an electric aerial etc

red wires in auto electrics is the nominal power wire. Use a circuit light tester and if it comes on when the ignition switch is on, or in the accessories position then that is the hot (power )wire.

Most likely the red one. black is ground yellow is memory.

Here are the colours of the factory radio harness and what they do.

The best thing to do is use a factory wire adapter. The main wires you need to worry about are power, battery memory, ground and speaker wires. If you have a power antenna you will need to wire in the remote (normally blue or light blue). The only other wire should be an orange wire for the dimmer on the radio face. This one is not necessary for normal operation. Make sure you have the main 11 wires wired in. Ignition, battery, ground and the 8 speaker wires.

try disconecting the positive terminal of the batery for sevral minets (5-10) this will reset the brain box memory for the stero aswell as for the car it self.

what caused the batery to go dead in the first place?
things that i can think of :
1) left headlights on over night
2) bad altenator not charging batery
3) battery is old and not taking a charge anymore
4) new stero installed incorectly and drainging the batery
have you resently installed a new stero or amplifyer?
is the turn key igntion system hooked into the amp/stero antena lead so that thy are shut of when the ignition is?
of note: new streo >theres a blue wire marked ant that goes to the amplifyer if not there you need to find the orange accsesory wire coming from the turn key igntion>check for power when ignition is in the on & off states could be yellow in some cars but is usaly orange if this wire has on and of state controled by the turn key igntion this would be the wire to tap into for the amplyfire and the radio main power
check your radio's instaltion guide for code errors
its posible that when hooking up the jump it was done incorectly and blew up the radio
ie postive and negative where fliped
hope this helped :)

From what you say I would check to be sure the factory stereo speaker plugs are plugged in tightly and deeply into the radio or radio harness. If you check this and still have no sound find the speaker wires at the radio and try to put an after marker speaker on the wire. There are two wires from the radio to each speaker so be sure you get the right ones. Let me know how this goes.

The prob seems like you have connected the power to your stero from the wrong place. You cut into live a wire for the power, this should be connected at the ACC on your fuse panel. Also make sure you stero has a good ground! Frankster016
