Electronic tacho for an a10

[Topdad]

Hi Musky, sorry my stupid way of putting things !! I should have said that I'd isolate the wire so that it just goe's to the new tacho unit . The one I originally was after ,advertised by Mike Hemmings a Norton/Norvil dealer used that type of Mag and said it worked okay but when I went to buy one the guy who made em had retired!!! been searcing since and whilst the guy in Holland is helpful his english is not to good hence my slow down on following it up. Well that and money ,a house move (and a wife who's going nutty from the house move ) , me going nutty from not being able to go for a ride out  ,I'd not reccomend a house move after 38 yrs to anyone. oh sorry everyone , rant over , padded cell next stop, regards Bob.
