Clipsal CBus L5508D1A 8 Channel 200mA dimmer shorting on one channel

Hi all,

I have a short and managed to isolate to one of the channels on my dimmer that is the cause.
I've disconnected the light fittings on that channel but its still tripping when I turn on that channel while the red wire is connected to that channel.
If is disconnected moved the red wire to a different channel, it causes the other channel the short so the cause must be on that circuit?
Is the something else I should check on the circuit to find the cause of the shorting?
Thanks

 

Managed to figure this one out. Followed the wiring and found a charred section that was causing the fuse. Replaced that section and all good now. Hope this helps someone else.
