Have found what I think is where the battery neg terminal attaches (earths) to the engine/gearbox and from that lead, at the engine attachment end, there is a lead going over to the chassis. This is all in the vicinity of the underside of the battery mounting tray. I have taken off the bolt and connections at the chassis end and completed the task as suggested above. Many thanks for that tip (just knew the vaseline would come in handy somewhere else!!). Also checked that no internal/external lights were 'on' when they should be 'off' and removed the non-OEM radio and assorted non-OEM fitted leads as a precaution - just the connecting blocks remain in place now.
Meanwhile have re-examined all the little jobs I've done recently to see where I may have not been fully hygienic on the elec front: me = new brake light sensor; new RH rear indicator lamp; RH front speaker wiring; airbag light on dash resolution (tighten connectors under front seats). Garage = new alternator and pulley assy. All were ok apart from RH rear indicator lamp - Py21W instead of P21w installed. New alternator is a neat job - no contra indications on the dash re charging light etc.
All lights on dash work ok apart from oil press light and oil level indicator which haven't worked for 4 years! Had also noticed recently the occasional slight elec shock/tingle when getting out of the car and touching the metal door to close it.
Upshot so far is that no more elec shox; all external lights now ok; oil press light and oil level indicator still not functioning.
Re-examined battery (new Nov 12) etc after last 'dead-car' incident and, from readings on the battery charger it now seemed almost completely discharged. (previous initial indication was that it was just about 100%). It has had and taken a full on charge o/n. Car started and ran well all day so far, but will leave it overnight and see what state battery is in tomorrow.
Now to see if I can get the fans to work - engine reach about 95degC today + 'STOP' light illuminated in dash. Cooling achieved through driving! Very appreciative of all advice so far .................
