Wiring Berco LED signals to Cobalt IP turnout motor

[juke]

I've attached a diagram that is part of the manual that comes with these Cobalts.

Unfortunately for me the Berco signals are wired the opposite way round to that shown.

I've got one to work by taking it apart and wiring it to be the same as the diagram.

Doing this took me quite a while and there's always a risk of breaking the tiny parts.

Can anyone tell me please if there is any way to use the signals by doing a mod of some sort without taking them apart?

Options: 

 

1 - Turn the diode shown around if the LEDs are connected with common positive  (unless that's within your signal and part of the faffy stuff).   

 

2 - Use the other switch contacts on the Cobalt motor to switch things.

Turning the diode round did the trick, thanks Nigel.

 

I had thought that might be the answer but didn't want to chance

trying it as LEDs are a bit of a mystery to me and Berko

instructions go no further than '12v DC only'.

I also emailed them with another question a while back but got no answer.

You're slightly over-voltage with a DCC track signal.   If you think the LEDs are too bright, then dim them by adding a small resistor (say 200ohm to 1kohm) in series with the diode.

The signals came with 1K resistors attached and they seem OK.

I hadn't thought about just one on the common side.

I'll change them to that when doing the installations.

Again, thanks for this advice, I'd been searching the web for days

but the combination of using DCC to power the points direct from the Cobalt

doesn't seem to come up a lot.
