I responded to your email Jon, send me your address in an email. I will get them in the mail tomorrow

Sorry, was off shift resting I responded tonight

they are boxed up ready to come to you jon......

I got a 624 that was a non runner because all the grease has dried up. After some gunk removal and lubricaton and it runs great now. 

I got the whistle relay installed but how do you wire it to pass power since it closes to ground?

I have done this conversion on the Seaboard 6250 NW-2. It's very easy, and is a lot of fun. The whistle relay usually only costs $20. You just have to make sure the relay is insulated from the ground in the locomotive frame. The contact tab on the relay gets soldered to the electrocouplers line.

Could you elaborate on the insulation and the contacts?

i have the relay mounted in a 624. The tab on the top I could insulate from the mounting frame I made with some thin fiber paper and over size the hole to make sure the screw doesn’t touch on the way through but would I then have to remove the end of the coil wire and connect it to the chassis separately for the coil ground and then have a “live” relay frame?

Similar electro-couplers used for Lionel and Lionel TMCC conversions operate at a higher voltage.  Most of the ERR and other TMCC conversions provided access to couplers.  There were different lengths of couplers for the different conversions.    This is an older Atlas SW9 that I upgraded, it did not have electro-couplers.  Atlas is another source for coupler parts.  Pictured is an Atlas articulated coupler, that flexes/pivots, two points, which allows better operation on tight curves.

I had used part of an Atlas coupler on a Rich Yoder 44 tonner.  The frame mounting of the existing coupler and unusual drive system made electro-couplers on this small switcher model difficult.

Note the length of the coupler beyond the model.  The small plastic sleeve over the coupler electro-coil is an Atlas part.

The mechanical thumbtack coupler was shorter.

I have 623 Switcher and a Lionel horn relay. I understand the wiring. I would appreciate specific help however on how to mount the relay in the switcher. Not much of a mechanical engineer or shop guy. 

Need an easy solution. 

Michael,

If you go to the All Gauge Toy Train Association web page, (www.AGTTA.com) and look in the Tech Tip tab for Teck tip #2, or the Newletter link for the April 2010 newsletter, there is a Tech Tip article on how to mount and add the relay.  In the article a metal bracket is used to attach the relay to the other side of the E-Unit mount.  Take a look, it might be the info you need.

Thank you. I had seen JW's article. That may be a little above my skill set. I would need remade pieces. 

pre-made

The 2330-125 whistle relay has a spring on the armature and does not depend on gravity. It could be mounted on its back with double stick tape. Just make sure the relay frame is insulated from the locos frame as the relay frame is energized. 

Will Teledyne uncoupling work with the ZW-L transformer?   and a  horn relay?

Yes. It will activate with both whistle & bell buttons.
