GGG posted:First, I would just unpower the Williams sound board to see if that resolves this. SInce your running conventional, both sound boards would activate on a bell or horn/whistle trigger. You did not say if this is steam or diesel. So the parallel motor trick only is good for dual motor engines (diesel).
Second, does this use motor power to a light via diode to get directional lighting? If so that is a possible source for constant bell. Or a stray motor lead touching the can of the motor. It does not take much. G
Thanks for your response'. It is a twin motor, 2 AC incandescent bulbs, non directional. I will follow your recommendations and see what results I get'. Thanks very much'..
