Hi, Well, finally got some time to work on this again. I hooked up the three wires coming from the main-section of the tach, but no go. With black going to ground, either with the blue going to 12v and/or yellow going to coil, I am getting no activity from it.
Someone before asked to know what brand tach, but in all honesty I don't know what it is. I was told it was a dealer installed tach, which could be completely false. I did take some pics of the outside of it and the inside of it. With the inside picture, notice the three wires. http://www.projectchevelle.com/gallery/main.php?g2_view=core:ShowItem&g2_ite mId=248 http://www.projectchevelle.com/gallery/main.php?g2_view=core:ShowItem&g2_ite mId=253 There are two red wires; one going to + on the instrument light and the other going to the internal body of the tach (could be ground as well). If anyone knows what type of tach this is, and maybe can help diagnose the three wires from the internal body (black,yellow,blue), I would be grateful. Thanks! -Graham 67 SS http://www.projectchevelle.com
