I have the following:


Edge


LFL Liberty serial 7846


Model SL8BBBB


July 2004


49 inch


Assy 967


Two 4 channel Liberty LED ballast 01-0285930-04


A 295 siren with lever switch and push buttons for lights


I unplugged the cables and removed the bar for a couple of months. I reinstalled the bar and do not see a place to plug in one connector. There is a black cable with many wires and a smaller gray cable. The loose connector has a green wire from the gray cable and w/blue, w/green, w/violet from the black cable. There is no voltage on any of the wires when all switches are on. The problem is the front corner LED's do not work. Rear corner's are OK. All corners are on the same ballast. I can not find this bar and I/O board on Whelen web site. I think all corner LED's worked when lever switch was in center position and all lights on in third position. All fuses on I/O board are good.

Update: Today the corner LED's came and flashed. Later they did not come on or just the passenger side worked. I swapped the power connectors to the ballasts and still had a problem. This shows me that switching and power are good. I also checked and had the same voltage on the power connectors to the ballasts. I had no voltage on the LED plug when it was not flashing. The front and rear LED's are feed from the same ballast. I think the ballast is intermittant.
