PW ZW transform shorting out on D handle

I think you'll have to take it apart.   Never seen that exact symptom, sounds like something is touching where it shouldn't.

Sounds like a wire came loose from the connection inside the transformer.

Did you check tightness of all the post? A wire may have come off from the post.

I will take a look at it again maybe I missed something. I did remove and replaced all the posts on the power and on the common, maybe I goofed. I will keep up the group updated.

A short in the back to the common busbar would do the trick, and those wires tend to come loose, the crimped connection on the posts is pretty pathetic.  You can buy replacement posts to retrofit any dead ones.

Did the transformer work before the update? If it did go over your work as maybe you may have a wrong connection some where. I have done this myself.

I've had similar symptoms when the insulating paper between the whistle/direction controller and throttle stalk wasn't exactly positioned after repairs.

Thank you one and all for the hints, tricks and advise on how to handle this situation. The problem has been fixed and for the benefit of all here is what happened. Gunrunnerjohn and ChooChooBob had the correct answer I goofed and placed the C wire in the D position and vise a verse. I took the time and looked up the scheme in my Greenberg's Repair and Operating Manual 7th Edition page 592 and traced it and that was the problem. I switched the wires to the correct positions and everything is good to go.

Dear Shawn and Gunrunnerjohn

I always replace the post if they need it or not and use modern crimping fasters to the posts. And just for good measure I use a lock or star washer for the nuts not to come loose from the post.

Dear bmoran4

I also originally thought that was the problem "insulating paper between the whistle/direction controller and throttle stalk" as well or maybe the Zenor Diode was bad. Either one of those situation would give you the same out come as well.
