Absolute Aspects, Ground Signals.

[davidtodd]

Hello Paul,

I am using AA's, 2-whites 2 reds,ground signals, linked to SC1. from Esu command station. (on programming track supply).

There are only connections, red (A), white(B) and a negative common (k).

I am not getting the white leds to appear.

Am presuming, AA. ground signal, requires another cable, positive anode to white leds,for (a). Figure 14, Page 16, SC1 ?

I have tested the ground signal on 9v dc. battery,with switched supply to both sets of leds, and is ok.

David.

Hi David

I think that you might have one of the signals that has the whites wired in series. These require around 8V to get the whites to light so do not light on the SC1 (which provides 5V max). You need the type that has the whites wired in parallel. I am sure that Matt will be able to sort you out a suitable exchange for the correct type.
