To be honest, Lucas electrics were no worse than many others 40 or 50 years ago.
Having restored and run twin cam 60's and 70's Alfa for many years, I can tell you
that Marelli electrics were far worse.
The only really properly sorted auto electrics at the time came from .de, as I
discovered later on getting a divorce from the expensive mistress and buying a
sensible but oh so relable Audi
