2002 R6 Electrical issues after standing for long time

Been looking through treads but cant seem to find anybody with the same issue as this.

All I can conclude is that the wiring harness is the problem so here is a breakdown of whats going on.

I have an 2002 R6 that has been standing for about 2 years now and I finally decided to fix it.
After installing a new crank, bearings (big and main), conrods, pistons and rings, I put the bike back together and for some reason there is no power to the clocks and the bike doesnt start.

I replaced the battery and checked the earth cable and they are testing OK.
I have also replaced the starter solenoid and all the fuses on the bike.
When I test the ignition, there is power going towards it and once you turn the ignition on it sends power through the main switch to the wiring harness.
The petrol pump primes when you switch the cut off switch on so I know its not that.
The battery is at 12.46v and I test the same on the ignition and other power terminals.
No leakage picked up either.
I also changed the 16 pin relay under the seat.
I have cleaned all the wiring plugs and also made sure that they make proper connection.

I have gone through the wiring harness just quickly and couldn't pick up any breaks or damage to it. It was never taken out of the bike and it was working before the crank seized.

Update 1

I tested all the plugs for power and opened the wiring harness up and all tested ok.
I opened the starter and it looked ok except for some wear on the centre shaft that connects to the brushes. I tested the starter directly connected to a battery and voltage meter.
At first the starter turned but very slowly and then stopped, I also noticed a dead short when testing the starter.
When I switch the ignition on I can hear the relays switching on and the petrol pump works so I guess its just coincidence that the clocks and the starter is broken.
I haven't had time to test the clocks but will do it when I get home from work today.

Need more bikes!!!

Good luck. When I restored my bike the best advice given to me was the KISS ideology.
K- Keep
I - It
S - Simple
S - Stupid

Read up on the diagrams and I am sure you will find your way.
