No such luck, there's a short, or a lose wire, or something that stops the "start" signal getting to the starter solenoid. I have checked every piece of wiring that I've done and they match the manual exactly. I will double check some things tomorrow, just to make sure it's not my fault :-P.
If I still can't figure it out, I will call Caterham on monday and see what they can do to help. I may end up just sending the car to them and have them finish it all up to the point where it's either ready, or almost ready for the road.
Until tomorrow! Here's hoping I can figure it out after sleeping on it.
