Tip & How-To about Car Audio & Video
Tired of searching for your vehicle in dash receiver security code after the battery has been disconnected? Here is a simple device that will keep that from happening.
You will need a cigarette lighter plug, a 9 volt battery snap-on connector, and a standard 9 volt battery. The snap-on connector can be retrieved from an old smoke alarm. Solder the connector to the two wires from the cigarette lighter plug; Making sure the polarity is correct ( + to + and - to - ). The center tip of the plug is positive and the two outside springs are negative. A piece of shrink tubing slipped over each wire before soldering makes a neat and safe connection. Connect a fresh 9 volt battery to the snap-on connector. When the vehicle's battery needs to be disconnected; Plug the device into the cigarette lighter before the battery is detached and power will be maintained to the radio.This eliminates the need to input a security code.
