Guide :Vehicle Parts & Accessories : XRS 9540 Radar Detector
Burned Cobra 9540
My Cobra 9540 detector stopped working and unfortunately it was purely my fault. I bought a hard-wire kit, wired it up, and it worked fine. Well one day I changed the location of the detector, thus moving the wire. When I plugged it back in and turned it on, I discovered that I reversed the polarity of the plug (It was a universal hard-wire kit with changeable plugs). It smoked, I was pissed. Oops. Any chance it's fixable?
