Hi everyone, Because of wiring needs, I am using the CU post from my modern ZW which uses the externally wired 180W bricks. My problem is that the whistle button does not activate the air whistle in the tender. I am assuming that the bell and whistle controls on this ZW are for either the AU or DU posts. My question is how do I activate the whistle from the tender without doing major surgery on the ZW? I thank all of you in advance for your replies.
