Hi folks
Long time lurker here, hoping I might be able to get some insight on an install I'm trying to do on a used utility my company just purchased from a neighboring company. Unfortunately they had stripped all the warning equipment from the truck when prepping to sell, not knowing we were interested in the vehicle. Fortunately though, they kindly included most of the gear in the sale including a Whelen Edge Freedom bar. Again, unfortunately it has fallen to me to reinstall and attempt to get it all working again. The bar is being particularly troublesome. It is labeled as an fv2RRRR model and has two cables running out of the bar one has what I assume to be the primary power and ground wires (larger AWG) along with a small unshielded wire. The second cable has the same small unshield wire as well as a small green and small gray (white?) wire which I assumed were trigger wires? No matter what I seem to try I can't get the bar to activate. I know it's getting power at the PCB since I measured 12 volts across the terminals and I've checked continuity on the all the wires. A few times I noticed the bar would faintly flash all the heads once when I initially provided power to the main +12v wire but that was all I could get out of it. I feel like I'm missing something simple but just can't figure it out. Any ideas would be appreciated.
Edit: forgot to mention I checked the 4 fuses on the PCB and while none were burned out I replaced them just the same.
