Before I cause my O22 switches to loose their magic smoke...

RichCOGR Forum Member

I need the expert opinions here. I have an MTH proto 3 ready to run set and have it attached to a simple loop of tubular O31 with a passing siding using a pair of O22 switches. I don't have DCS, I just have the Z500 brick and wireless receiver to control the locomotive. The switches I have connected to aux power to my 1033 transformer. I am using common ground from the MTH brick and the 1033. I hooked up one O22 switch as described for constant voltage everything was great. I hooked up the second switch the same way. Tested the operation of both switches using the 1033 and both worked as they should. I plugged in the MTH brick and I tripped the breaker on the z500 brick. Not sure what caused this, but it acts like voltage leakage but I don't know. Any thoughts?

This is a very difficult combination to phase properly as you have proposed.

The first obstacle to overcome is to realize that "A" on the 1033 is the common, not "U".

Then, phase the track outer/running rails to the 1033 "A" post, use "U" for the 022 fixed voltage voltage plugs so you can fine tune the switch operation for a nice "snap" at the lowest setting.

It's always nice when it all comes together on the first debugging attempt!
