Whelen Light Bars

[Firstresponder25]

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 .

Great, thank you!

Tried the wiring schematic and still cannot get these bars to work. So, I am hooking the red to power and black to ground and get nothing, any ideas what I am doing wrong?

How many wires are there? Can we get some pics to try to help you decipher what steps to take

So as I said previously the Red/Black wires will energize the bar when connected to a power supply. Functions are triggered by applying voltage to the smaller bundle of wires individually to perform other functions. I think I have a YT video on a liberty bar I was working on.. try this..
