Fixed my Tacho tonight thanks to Joe he told me to change the 2x 1 farrad 25v capacitors on the back of the Tacho and although it was a bit scary because I haven’t done a lot of soldering on electronic boards before (by a lot I mean none) but I had a crack took my time and for $2.20 my Tacho works perfect thanks so much for being there for us Joe !
