Delbots Help!!

Hi, can anyone help me with this lil problem? I have a delbots mk2 interface connected to two 4qd NCCs. The ignition terminal block is wired over, but when I apply power to the 2 NCCs nothing happens, even with a full forward signal and/or adjusting the trimmer- no lights, no movement. Theres definatly power running to the speedos, because when i disconnect and reconnect the battery connecter, i get a spark. One point I think may be causing the problem is, because my input is already powered and doesnt require the BEC on the interface, i have only connected ground and signal. Would this make any difference?

Im fairly sure it would .....
Why not connect up as per instructions?.....or have you got this already?

I used to have that board and if i remember right, it wont do anything untill you connect everyhting up to complete the circuit.

Woody... The input im using isnt actually a reciever, its an RS232 servo controller board (my bot uses an onboard computer) and the board uses its own 12v input.
Cheers Chris, ill give it a go, anyone any idea where i could get a couple of female to female servo leads? hopefully it wont cause any problems with the two power sources :S

You were right guys, It works great now. The two power sources dont seem to be causing any problems either (yet)

Glad it works..
Merry Xmas.
