hello guys, i just installed a NCE SW9SR decoder in my new proto 2000 switcher. it runs fine, but i have not yet been able to get the head ligt to shine. i have wired it exactly like the directions say and even tried several different bulbs just to make sure it wasnt it. it will not come on at all and i have checked and re checked but im haveing no luck. im no pro at this decoder stuff and im sure im overlooking something, but im not sure what. is there something i have to do as far as programming or should it be set as default? any ideas are really appreciated. thanks!
