Wiring a Switch for a Radar Detector
Jeff, when wiring a toggle switch for the radar detector it is not necessary to wire the negative wire to the switch. What is happening with the way you wired the toggle switch is that you have created a direct short, or a direct path from the positive to the negative and this is causing the fuse to blow. The toggle switch should be wired so that the positive enters one terminal and the other terminal is used for the positive wire to the radar detector. The negative wire for the radar detector should attach directly to the negative wire for the radar detector.
