I have several Lion Chief Plus engines, and on about half of them, the electro-coupler has stopped working. When I double-press the coupler side of the remote button, the bell rings, but no coupler. In all cases, I have tried the Universal Remote- same results. In fact that Univ. Remote works on engines where the engine's original remote still fires the coupler.
What can I try, with my limited electronic knowledge, to solve this issue??
