JFC454 posted:Thank you for that information. So that second transformer could be an unused throttle on a ZW-L instead of a PW180?
JFC454, Yes. Plus the unused throttle on the ZW-L can adjusted to fine tune your DZ-1000s.
John, I still think 18 volts is a lot to operate a DZ-1000. Maybe you need to check your RossPlate switches to make sure they are operating smoothly.
