Main dipped headlights not working

Hi,

Thank you for the replies I have been on the car all day today so here is what I have found and I will read through comments in depth shortly.

This is my wiring - I have done the MAD 'upgrade' and cut out the AMP gauge.

I have had the entire wiring loom apart today, found all three splices.

Here is a video of the car with the 'flashers' on. You can see they are flashing randomly but they do work.

The new fuse box, I have checked this 20 or so times that it is the same as the original.

I found this splice under the dash. I disconnected all of the wires in order to try and find which circuit was at fault.

When the two on the left were 'rejoined' to how they were (factory splice) the reading on the gauge drops and pulses...

This image shows the red cable from the starter relay +, then to the black cable (as the amp gauge has been bypassed)

I do get a reading on the plug which goes to the foot pedal switch when the dimmer switch is pulled out fully, only 5v though not 12. HOWEVER, when the plug is in the switch I get 0V on the same connector.

The lime green wire going to the dimmer switch for the low and high beam was burnt in the dimmer switch (where this photo shows the test probe in) I have now fixed this with a new connection.
