For what its worth a few years ago I had a similar problem. Turned out the car 12V socket I was plugging into didn't work. Quickest way to figure that out is to take it to another car and try it there.

How do u get it to work

Which model? Simply take the unit out of the box, mount it, plug in the power cord and turn it on. That is all that you need to do. remember this unit is a RADAR detector and not a POLICE detector. The officers have to be transmitting to have the unit pick anything up.

check for power on the line you may have popped that fuse if fuse ok than you more than likely burnt up most of the electronics in your detector

Need to work a RAdar detector: whistler 1430

Does the unit turn on when you plug it into the lighter socket? If not, does the lighter socket power other 12 volt devices? IF the lighter socket works and the radar detector doesn't there is a fuse in the plug end of the power cord. Unscrew the tip to expose the fuse. Replace it with a 2 amp fuse from any auto parts store and try it again.

What wire do I choose

Your 8500 X50 draws less than 1 Amp of power. The best solution for hardwiring your radar detector is to purchase one of Escort's direct wire kits and then use an Add-A-Circuit (available at almost any auto parts store) to tap the direct wire kit's power into one of the vehicle fuse box's switched power fuses. I recommend tapping into a fuse which is rated for 10A or higher since the higher amperage fuse terminals have thicker wires running back to the car battery, and this generally provides cleaner power for the radar detector.

Cobra XRS 9950 Radar Detector not powering up

At the end of the power cord for the radar detector the end screws off and there is a fuse for the radar detector itself. Check it....

If that isn't the problem post back for further help.

Thank you for choosing Fixya!

Continuous alert

About the only thing to try with the Escort 8500 and the x50 is to do a full reset. Hold all 3 buttons down while turning the detector on. I believe Escort will still work on it, there will just be a service charge with no warranty.

Does not work

Check the power lead - if it is a cigarette lighter socket type, often you can unscrew the end and you will find a small fuse in the plug - this could be the problem. If not, then is the detector still under warranty? if not open it up and send us a couple of photos of the insides. Hope this helps :)
