CW-80 and O72 switch - AC/DC?

Are you sure you're not hooking it to the non-derailing outside rail?  Try connecting the power to the incoming side of the Y.

i'm using the little pin I plugged in that the switch comes with (constant or direct supply pin i think it's called?) so I'm not sure if it's hooked to inside or outside rail. As far as ground i tried both inside and outside and same results.

The accessory voltage is adjustable on a CW-80. Maybe the voltage is set too low. Try hooking it up to the track voltage connection at full throttle and see if the switch works. I don't remember how to adjust the accessory voltage, but I know it involves holding a couple of the buttons down and pushing the throttle to the desired output.

Thank you so much for your troubleshooting help.

 

I did try on full throttle track power also. Same buzzing result.

The reaction suggests that the switch non-derailing feature is engaging and forcing the switch back to the one position. 

You don't need to connect both accessory posts to the switch, just the non-common(power) post. The switch will receive common through the track rails.

 

Which lead right into the next series of questions, all of which must be answered to solve the problem - what is the date code on the CW, which post(s) are you using for center rail & common, and which post are you connecting to the aux power pin on the switch?

 

Your binding posts, 4 of them, are identified as(viewed looking at back):

 

Red A   (Track)          Red B(Accessory)

Black U(Under A)          Black U(Under B)

Unless he is not following the proper common ground rules for the different versions of the CW.

Perhaps pictures of the connection would help.

 

jay,

Look on the bottom of the CW-80 and find the letters/numbers. Tell us what that is and then answer Rob's questions.

See attachment CW-80 and track.

 

Red A (track) connected to center rail,  black U connected to outer rail, red B (accessory connected to track pin on the switch, black U tried both connected to outer rail and not connected at all. Thank you all for your help again.

 

Important question.  Do you have the insulating pins in the proper rails on the out side of the switch?

 

 

that's it isnt it. Originally no, then I could have sworn I did but now can't remember. I will go back and do that. i think you figured it out. will let you know

If the insulating pins are not in the proper place, you'll get exactly what you describe.

 

OK - that is the newer version. The two black posts are common, so you have the right connections.

That was it. I had them on the outer rails and that was incorrect. Switched them over to the inner rails and works perfectly now. That you so much for your help all!

We love the easy ones.
