Had a long time MF mechanic look at it and his experience is that the electrical path between where the battery is grounded and engine deteriorates with time.
My neg terminal is now grounded to the engine.
Cranks much stronger but not fast enough for a start. Starter getting very hot.
May have to return my new starter, I'll keep you posted
