Funny thing is all the cars in my younger days (up until late 20s) were BL or BL Descendant machines with loads of Lucas badged parts all over - Metros, original Minis mainly. I can't think of a single time I had an electrical failure apart from water in the distributor in a mini which was cured at the factory with a bit of hardboard, and at home with a rubber glove with the fingers removed.
As soon as I got into old MGs and started getting "improved from the original Lucas design" parts I was stranded often - coils, distributors, non-working lights at night - all sorts. It was a little like the MGOC wanted you to have the full "period" experience
No smoke though, thankfully.
