Funny thing is I also worked at a Dodge dealer for 24 years and when they started using the 3 wire Hall Effect unit in the dist one of the Mopar tech guys told me its better then the AC pick-up because it uses a higher voltage (5 volt signal wire) then the AC pick-up thats about 1.6 volts AC signal so it wont be effected by a dirty connection as easy. So I thought we would not see many AC pick-up units much more but thats not true as many still use them so I guess the Hall Effect is not all that much better. Ron
