Peco SL-E99 3 Way Point Wiring

[paulypaul0]

Hello Everyone,

 

I'm returning to modelling after a break of around 25 years, and am struggling with the wiring for this item!  I am going for traditional DC, mainly as I understand it better, and I'm on a tight budget.

 

The space I have means I need to use a 3 way as I don't quite have room for 2 "normal" points.  I've searched the web but cannot find a good answer to my question, which is how best to wire up my SL-E99, which will use Seep point motors.

 

I understand the wiring to make the motors work and can do that bit with SPDT switches (like the Gaugemaster GM510), but I'm struggling with switching the polarity of the track

 

I've discovered that when the switchblades are set to go "straight on" it works fine, but when switching to either left or right I'm obviously going to have to do something with the wires that come trailing from the 2 frogs to make it work properly, but I can't get my head around it.

 

Has anyone done it with this model of point and could post an exact diagram or information on what to do.  Ideally I'd like it so that when I throw my switch (GM510 or similar), then it switches polarity for me too.  I understand the concept of isolating rail joiners and sections  - it's just this 3 way I'm stuck on!

 

All help gratefully received - be gentle with me!  Electronics is not my strong point!

 

Many thanks,

 

Paul

Thank you.  I see myself spending a fair bit of time reading those pages, but a quick skim through tells me I'll be fine - I think!

The Peco diagram is fairly clear in that one switch powers two frogs.

Although it shows Peco motors/switches, it shouldn't be any different using any other point motor/switch methods

Best advice is to wire one switch at a time and check as you go along.

If it shorts - swap the track feeds to the switch.

 

Cheers,

Link rot has set in, you'll get a 404 if you try the link quoted. Try this one instead https://www.brian-lambert.co.uk/Electrical_Page_3.html

It's best to wire 3 ways so the wrong motor can not operate on its own or it can bend the point blade or pop it out of the tie bar.

 

I use capacitor discharge and have wired the motors so as to ensure this can't happen.
