Hmmm! Thanks for all that some (most)went clear over my head.all I want to know is anyone seen this 'new'hei set up?I've had enough of points creeping,condensers giving up after a few months,its not that easy getting the spares over here,for me the nearist is a 2 hour drive away,and postal rates are stupid, & if you get the right thing your lucky,so I want to modernise for reliability,ever tried resetting the points at the side of a highway with trucks missing your backside at 70 mph,the trucks not your backside..I've tried email langdons. no response....which is another whinge for another place.
