Thanks for your help guys,
I had connected everything correctly
The problem was that the sandwich plate wasn,t earthing to the block/chassis, so I,ve ran an earth from the sandwich plate direct to the chassis & it all now works
Oil temp is showing a reading, tho can,t get it up to full temp as not allowed to drive it yet,
Oil pressure is showing between 25 to 30 at tickover & between 60 to 80 at high revs.
Yet again, this great forum came to the rescue , thanks everyone
cheers
andy
