Finally got an afternoon to do some repairs...
I need to open the engine back up and shorten how much wire is sticking out. My new tether has an extra pair of wires, so I intend to add a switch to turn the smoke unit on and off.
Now I still have a weird thing to deal with. For some reason the whistle is going off when the bell button is pressed and vice versa. It was doing this before the plug broke off, since the last it got serviced (by someone else).
If I swap the leads going to the sound board will this be corrected?
