2010 fe390 cranks but no power to fuses = wont start!!

As the title sorta says, i have a 2010 fe390 that cranks over really well, but there is no power to fuses 1, 3 & 4, so no fuel pump or lighting and wont start. I have searched on the net and tried a few things, like put power direct onto no 1 fuse and the pump primes up no issues.
I also have power going to the regulator, but no power out of the regulator when cranking.
There is voltage coming from the stator when cranking as well
The white/black stripe wire has no breaks from the regulator to the ecu and the brown wire goes to earth.
Everything points to the regulator for me, but i am hopeless and not very confident when it comes to electrical, so really hoping someone can help so i dont start spending money on maybes and parts that possibly arent the issue!!

Have been doing wiring inspection, havent got to where it runs over the motor yet, but havent found anything yet
When talking about the power relay, where abouts is that located? All i can find is the starter solenoid, and the indicator relay. Havent been able to find any other ones?
Have a new on/off/start switch on the way, but havent recieved it yet...

Thats the part number for the relay i believe could possibly be the issue, but i think the pics are of the tip over sensor. I think i have finally found the power relay, next to the coil in behind the left side radiator....bugger to get to, but if its it its a cheap fix for a genuine part...
Will get one and fit when i get back from overseas...

Searching the part number so i can see what it look like, it is the one next to the coil!!

Ok. Relay is working fine when tested off the bike. Seems i am not getting power to the relay via the red and white wire. I cannot find where the other end of the red and white wire goes to, going to study the wiring diagrams...

Problem found. Where the whire/red wire connects all up in the main loom (roughly where the 'p' clamp / bend behind the fuel tank) the teeminal had corroded and they were all barely holding on, with the one for the relay off completely!!

Thank you for all the help [emoji4]
