Again, you have a ZW-C electronic controlled ZW variant. It's possible, even likely you might have a stuck on or partially stuck on output due to a transistor failure or other failure.
That could easily explain with the whistle and direction lever is not working- the control board has failed and you may have partial or full throttle condition and no way to cut power or apply DC offset.
Sure, you could do work arounds and use an external whistle diode setup and or a switch to make and break power. I get trying to get by with what you have, but again, this sounds like just another failed ZW-C topic.
