SHY 7G 2 Posted October 11, 2019 Hi all would anyone know which terminal connection on the ignition switch Connection 4 from the tachometer should be connected too? Below is the Veethree Diagram showing the electrical connections, Does Connection 4 from tacho go to ACC on the Ignition Switch?? Any advice greatly appreciated.

western 679 Posted October 11, 2019 Never heard of those make gauges before, most rev counters for diesels connect direct to W terminal on alternator, & a earth/12v feed for the lighting Quote Share this post Link to post Share on other sites
hurbie 51 Posted October 11, 2019 (edited) connection 4 should go on the "ignition" position of your ignition switch (+ 12 volt when switch is in the normal "engine is running" position) Edited October 11, 2019 by hurbie Quote Share this post Link to post Share on other sites
