Rover 418 sd turbo 1995

I have nearly completed a restoration of a rover 418 sd turbo but encountered an electrical issue. I’m no auto electrician so need some help.

no glow plug light on ignition
Clicking from relay behind the dash below the radio
No turn over
no Power to the diesel stop solenoid
power is going to the starter motor
Glow plug relay is good
Changed other relays in the engine

Do you have any ideas of which I can check out?
