12v Level Crossing - lights not flashing, problem now solved.

[Andy Glascott]

Hi all, another appeal to the collective EB mind, maybe particularly to my fellow 12v enthusiasts.

I'm installing all the wiring and controls on my new layout, and the lights on the level crossing don't flash. The flashing is controlled by this piece, and I suspect it's just getting old.... (I probably bought it 35 years ago.) Have any other 12v fans had this issue? Is it solvable? I've tried the usual checks of reversing the plugs, connected a light directly to the unit on a single short wire etc, but they will only come on and stay on rather than flash. While I'd rather not open it, if it's possibly repairable I'm willing to try, because I don't need it to just have the lights on.

Alternatively, is there a simple piece of electronics I could wire in between the control unit and the lights to add flash back in? (I have little to no soldering skills.)

Thanks,

Andy

Ok, update already.... When I looked at this listing for a replacement the seller mentioned turning the unit upside-down. And the light flashes..... Any thoughts?

Update 2 - The control buttons are a distance away from the 12v power pack, so connected via a wire. Switch the plugs on that around and the lights flash.... Feeling slightly dumb, but rather than remove the post I'll leave it up to hopefully help others out.
