Turn signal switch replacement failure

Hi all,

Excuse me if this is a double post but I don't see my post from last night. I am trying to replace my control head turn signal switch which does not seem to be working with a 3 position on-off-on single pole/post? double throw toggle switch. There are three posts on the switch. I have power coming from the flasher unit to the middle post which I would think is correct. the left and right posts of the switch are connected to the Green/Red (left side) and Green/white (right side) wires that were the same that the original control head switch wires connected to. Two of each Green/White, Green/Red. At the flasher I have power on the left post that comes from the fuse box. That power passes through to the right post and ends up at the middle post of the new toggle switch. Is that not the way it is supposed to work? What is not happening though is when I toggle the switch in either direction none of the three posts on the switch are hot. All are off. What I thought should happen is that when I throw the switch to one side or the other it will connect the 12 volts to the left or right turn signals. It doesn't.

The turn signals were working very recently and I did the test in Bentleys where you jump the left and right posts on the flasher to see if it is the flasher or the switch in the control head at fault. I also have an extra flasher that I tried. That is where I got the idea that the switch in the control head is not working.

Is my simple SPDT switch not up to what I need? I was so proud of myself for seeing the diagram and recognizing (I thought) that the turn signals were a simple SPDT switch.

Anyone know where I am most likely to have gone wrong here?
I am going to replace the original control head switch and am not squeamish about removing it but I have been spending alot of money on the car recently and need to take a break for a while.

Thanks very much,
Jim Lee
