I'm a newbie with a ZW setup. Have installed a brand new ZW unit with both of the 180 watt transformers plugged in to the unit... Oh hell... there is no output from the ZW unit. I've tried using both the A-U circut and the D-U circut. My Fluke multimeter reads no output regardless of the throttle position. 0%, 50%, 100% nothing. The green light is lit. Once while cycling the power switch on the transformer off/of/off/on for maybe a second there was power. Any thoughts out there in cyber space?
