The police department this bar came from initially used the Federal SS2000SM to control the Whelen Liberty bars when they first got them. That entailed having a separate cable coming from the SS2000 TA plug into the bar, and splitting off to the 6 rear light heads.
The minute I turn on the power to the SS2000, the four middle rear lights turn on solid. Before I activate any switches. When I do activate the TA on the switch, the outside rear lights (1 and 6) flash but the center four stay lighted solid. If I disconnect the second wire coming from the I/O board to the light modules, all works fine. When I disconnect the power cord from the I/O board the lights work in the TA function as intended.
What am I missing here? It's not a ground issue. It's like the four middle lights are getting power from the bar I/O board. The bar functions normally when the TA wires aren't connected.
Any thoughts?
