Radio/CD player is Dead 2003 Expedition

[Johnny Be Cool]

I made a mistake and borrowed a battery from my Mustang and did not realize that the terminals are different. When I put the cable on I got a big spark and took it off right away.

Now the radio doesn'tt come on or light up. I took the radio out and see no in-line fuses.

I also notice the 4x4 selector does not light up on the dash and it doesn't shift to AWD, Hi or Low. Lucky, it's in AWD. I don't know if this is related to the battery mixup.

Where else to look.

Thank you!

start checking fuses related to the problems you are having or check all fuses just to be sure.
for the radio check F1.4, F1.22, F1.7, F1.31
for the 4x4 selector check F1.11, F1.115, F1.120 and check the operation of the Accessory Delay Relay

Aww I was gonna say it's a good time to upgrade to a better head unit. I just upgraded to a double din jvc Bluetooth/mp3 player. So much better.
