I am trying to put this whistle together. It came to me in pieces. From the diagrams on Olsenstoy.com, I thought I had it but alas, no joy.
My first question is why would the whistle blow without the relay connected? Obviously the circuit is complete without the relay, but I am trying to understand what is going on.
From what I can see, the ground seems to connect through the screws holding the whistle assembly to the car platform. My second question is should the screws be insulated and the ground make contact at the base of the relay?
Thanks for any help.
