You know, I thought that for years. Certainly nothing Lucas made worked. But it was even more systemic than just the Lucas parts. I think they had infiltrators in their plants, maybe from the Germans, sabotaging everything they made. Think how easy it would be. Five or ten auto workers in the UK getting an extra 1000 pounds a month, cash, from MB?
If a Jag drove, handled and had the dependability of a MB, I would not have bought 6 MB’s in the last 10 years.
Although, my 1988 MB 560SEC is the best designed and manufactured car ever made.
Your they is possible but in plain language, Lucas parts were cheaply made and little was done to test quality due to union interference plus onerous taxes.
Just compare the windings in a Lucas alternator vs. Delco-Remy of the era.
A buddy in the sportscar repair biz had uncovered a Lucas to Delco of England cross reference booklet. Surprisingly, many of the Delco parts could be found in US auto parts stores.
Therein was the solution to starting, charging, etc...
