Put new oil in, after new filter eventually turned up. Put the wiring loom back in, battery holder, and all associated wiring in that area, then absolutely no life whatsoever, bugger! Took it all apart many times, couldn't see anything wrong. Left the ket turned on and just keep proving and pressing wires, then some life, yellow really would click and neutral and oil light would come on if I pushed the loom just above clutch where it splits into 3 or 4. Cut the plastic wire cover off and found a white wire not attached, it should have been joined with the other white wire, but had corroded off. I assume it was fine and contacting enough two work until I took it out and re-fitted it. Cleaned it up, chopped the joiner off the other, soldered together, now all good, so after several hours now happy again. The brown dried dust/ muck on the floor in pic 2/3 came out of the plastic wire shroud as I cut it off, not ideal for wiring.
