I picked up a couple of older Whelen Edge and LED Liberty bars the other day. Tried hooking them up to a converter and would not work. Tried hooking them up to a car battery and battery charger with still no luck. Looking for suggestions.

Most Whelen lights require constant power to primary red wire + and the ground typically black. The other wires in the bundle are typically trigger wires for specific functions. Best advice is to try and pull a model number and lookup a wiring schematic, so you do not accidentally blow something up .
