Guys - I purchased an new ZW-L just three weeks ago, and today it looks like it may have to go back to Lionel.
Here's the deal - I only use the A-B (right side) Output posts - I have NOTHING connected to the C-D (left side) outputs. When I turned the ZW-L on this morning, the voltmeter for the C-D was dark - as if a circuit had been tripped. I double checked all circuit breakers, used the reset intructions in the manual, threw a little pixie dust on it, and still, the backlight won't come on. By the way, the red light is NOT lit.
In addition, when I push the D Throttle lever forward, the volltage output registers on the darkened voltmeter - even though nothing is connected to it. Previously, if I pushed that lever forward, the voltmeter continued to show zero output - I assumed that was because I had nothing connected to the D posts. Also, if I push the C throttle lever forward, the C-D AMPMETER registers amps - and again, nothing is connected to the C-D posts.
I should also note that I have the ZW-L connected to a very good surge protector.
I would appreciate any advice you could send my way.
