This is probably simple for you guys, but I'm stumped. I've got a Code 3 3672L4 siren/light controller with a Code 3 siren (can't tell the model from where it is placed in my little Impala. The siren quit working, but if it is totally quiet, I can hear the tones coming from the controller and even from the siren itself. I cut the wires and attached them to a dynamax. It worked for a second and then it too quit. I have checked every fuse I can find and there's nothing blown. Any suggestions?
