Need a little help with electrics.

Hi all,
I need a little help in diagnosing. I have some ideas but want to bounce it all off of you guys before I start buying stuff.
I have a 66 Series 2 Elan here. I bought the car after a complete restoration, chassis off, dash out, etc etc.
Car was rewired with new harness.
I am getting no power to the fuse box. I do have power to the solenoid. I can trace the power from the solenoid to the control box. There is power there. But I have no power at the brown yellow OUT at the control box that I believe goes to the ignition switch.
I don't know if there is supposed to be power there. I have not checked power at the ignition switch.
Anyone have any ideas. Is the control box bad? Open to ideas.

Doing a google[lucas control box testing] throws up lots of possible information.
This may be the most useful one:

And this one explains how it is supposed to work.

Yes, it is a dynamo or what we call a generator.

Assuming the replacement harness uses the same wire colours as the original, the brown/yellow wire you refer to is the output from the generator and will only show voltage when the engine is running. It's the brown/blue wire which is the feed to the ignition switch. If the engine starts and runs OK then this feed to the ignition switch must be intact and the fault could be a poor contact within the switch, the terminal connection to the switch or a break in the wire somewhere between the switch and the fuse box.
Are you 100% sure that you have no feed to the fuse box? Cleaning the terminals and the actual fuse carriers can often be all that is required.
Hope this helps.

Thanks. Just saw this. I took this picture on my way to work and was going to ask exactly what you answered. Must be a problem with the ignition switch. I get 12 volts at the brown and the brown and blue wire but nothing at the brown and yellow wire, which you say is correct. I will look at the ignition tonight.
