I have a 275 watt ZW transformer. When I check the voltages on all the outputs on the voltmeter, it shows that all are working properly measuring 20 volts. As soon as I hook it to a track and place an engine on the track, it goes into a dead short. The red light comes on. I’ve tried multiple engines that I know work perfectly on the layout, but as soon as I put it on that zw, that’s what happens. Any ideas?
