I can't get RP to fire the coupler with the +5v. I have read those older MTH couplers need 12v.
Has anyone successfully hooked up electro couplers?
Thanks.
Ron

For your situation, you could put one on the output wires going to the couplers. As far as I know that should work.

You can always look into a voltage step-up converter. Pololu makes some that are small are easy to use. I had to use a 3.7 to 12 volt converter for my battery powered locomotive. The battery only puts out 3.7 volts but the LM needs 12-14. Works like a charm.

I never heard of such a thing. I'll look into it. Thank you.
