ZW Wire on bottom of Primary coil

Jamie GirlJamie GirlOGR Forum Member
All:
I replaced the cord on my postwar ZW and had to remove supporting brackets. When I went to re-assemble, I noticed a copper coated wire from base of primary coil had come off.  I am not sure where it should go and was hoping someone could view the attached photos and advise me where to attach it.  I have the Greenberg repair book but it doesn't show me enough. It looks like it might solder to center of what I think is the breaker, but not sure and I don' want to get it wrong.
Any help much appreciated!

Thank you! The diagram was exactly what I needed.  It is wire 1 and it does go to the point I thought it did.  With this wire unattached my output voltages were topping off at 12V and the "on bulb" for the green light was off.  I attached a test lead to the point indicated in the diagram on the middle of the breaker and a second lead to the solder end of the wire from the coil.  Joined the two leads and voila! I got my 19 volts secondary output back and the green lamp bulb was back on. So now I just have to re-solder these two points.

Thanks again!
