Thank guys, as Dr Honda cautioned about the care needed to not damage the sender when putting it back in, I was hoping for a easy test to see if the buzzer was at least working. Taking flowmasterman's advice, I disconnected the wire from the sender and touched it to the prongs that you attached the spark plug caps to when they are removed from the plugs. To get the buzzer to sound, I needed to touch the starter button with the lanyard attached. The engine briefly turned over and the buzzer sounded. While I don't know if the sender is working or not, at least the buzzer is.
