2K radio does not power on

[btroy]

Hi guys, got a quick question.

I had installed an aftermarket radio in my sons Taurus and all was well. Now I reinstalled the original radio and reconnected the wiring harness in the trunk. now I have no power to the radio.

Could someone please help me to identify the power wire (color) that is for the original radio?
What fuse controls this? Owner manual has been lost.

Thanks in advance.

Just take a test light, and put the clip to a good ground. Then probe for the wire that is hot with the key turned back to accessory(this one is for radio power). Also look for one that is hot all the time(this one is for the clock and station memory).

I'm not familiar with your vehicle I was just giving basic advice maybe someone that knows can tell you exactly which fuse, or you could just check all your fuses, you don't have a cover for you fuse panel that shows you which fuses are for what?

Also too make sure you have your clip on a good ground, if your cigarette lighter works you can verify this by sticking the probe down the middle of the socket and touch the center and it should light up. If it doesn't then place the alligator clip somewhere else, you could clip it to the side of the cigarette lighter and use the probe then to find your hot wires that need to go to the radio.

You also need to check to make sure that you have a good ground going to the radio. But if the light doesn't show up when checking for your hot wires it's a fuse somewhere.

thanks for the general info on troublehooting. I understand how to do that.

No the fuse panel does not have a cover.

This is why I posted in the Taurus forumn, still needing the fuse postion for the radio. 2000 Taurus

Is it the radio part of the Integrated Control Panel (ICP) that doesn't power up, or the Rear Control Unit (RCU) that doesn't power up? The "radio" is actually in the Rear Control Unit.

I don't have the service manual for the 2000, but do for the 2002 which is probably pretty similar. Power to the ICP is via fuse F2.27, 10-amp, and is a red/yellow wire at the ICP. This wire is hot in Start or Run. Fuse F2.16, 15-amp, also provides power to the ICP via the white/red wire. This wire is hot at all times. Finally, fuse F2.11, 15-amp, provides power in Run or ACC via the black/pink wire. All three of these fuses are in teh Central Junction Box.

The RCU receives power via two fuses in the Battery Junction Box, 5-amp fuse F1.27 and 20-amp F1.17. F1.27 provides power to the RCU via the Red/Orange wire, which appears to only be hot when the car is in park or neutral and the Starter is engaged. Power to fuse F1.27 is sourced through the Transmission Range Sensor from fuse F2.37 (15-amp) which is only hot in Start. The yellow (or could be red/yellow) wire via fuse F1.17 is hot at all times.
