Thanks for the replies. I ordered the Carling Contura single mount from Mudstuff. It came within a day or two - so fantastic service.
Right back to the drawing board. The Ribcraft console is as tight as a gnat's chaff. I was looking at it again last night and did a bit of adjustment, but still no success.
I double-checked the switch - and I've posted pictures. The Carling switch has four spade terminals on the reverse, not three as I'd originally remembered. Not the best picture - I know, but you get the general idea. Two spade terminals are at the top, and the other two are in-line on the left hand side. The white stuff isn't expanding foam - it's just a little Sikaflex. To avoid confusion (on my part), can we agree terminal top left is (1), top right is (2) and the lower spade terminals are (3) and finally (4) at the bottom left.
I did as you suggested Erin
, and have run a black wire direct from the battery -tive to both navigation lights in sequence.
A red wire connects both navigation lights in sequence and runs through a small-fuse box with 5 amp fuses. Again spade to be confirmed prior to connecting to switch?
There's a small gauge red wire from the battery isolator which will need to attach to the switch. Spade to be confirmed?
You will also need to connect battery neg to small neg wire in carling light to allow the light to operate.
Can you confirm which spade this would attach to on the switch?
