Problems starting and temp gauge issue after work on instrument wiring

Re my post above, when trying to sort my starting issue I made up a little jumper cable and plugged one end into the brown live feed [ at relay position] and touched the other end on the white/red to solenoid. Started every time.
Connected small white from ignition switch through a test bulb to the earth [ earth can be tested by connecting bulb brown to black]
This proved there was no power in small white when key turned. I changed ignition unit but this did not help.
This proved issue is/was in the white cable. I did not want to waste time sorting that so.
My fix was to run a cable direct from the white wire position on ignition switch to the starter solenoid. It only needs some 5amp to activate starter solenoid.
Why there is a relay for this job I cant think. Older cars have direct line from ignition to starter method.

Nothing else clicks near my fuse box(early glass fuse type)

Thanks for this. Totally clarifies what should be happening. Mine's slightly different in that the Brown/Red is white in my case. I think my relay has 5 terminals but the one in the middle doesn't seem to have a connecting cable.
