CamH Posted December 3, 2007 Share Posted December 3, 2007 Hey guys, My tach hasn't worked since I picked up the car and I've just finally got around to messing with it today. The car is a '73 with a crane cams XR700 ignition system. I've been trying to use the guide located here: http://www.zhome.com/ZCMnL/tech/ZXPertronix.htm but it does not seem like my car has the same colors as the ones listed and I don't really want to ruin anything. I included some pics of what I'm working with here, if anyone would know what to do from the top of their head that would be great, if not I will probably just end up swapping it out for a 280Z tach - I just want to avoid putting in that kind of effort. Also if more pictures would be helpful let me know. Thanks! Quote Link to comment Share on other sites More sharing options...
gjc5500 Posted December 10, 2007 Share Posted December 10, 2007 When i hooked it up all i did was unhook EVERYTHING dealing w/points(including condensors) and went red to + and yellow to - thats all you have to do and the tack will still work.

CamH Posted December 11, 2007 Author Share Posted December 11, 2007 Thanks for the suggestion! The car came with the ignition when I bought it, and I am unfamiliar with the points style ignition. Could you please point out to me which pieces I should try removing because I am not really sure what went with the original points system that I can get rid of. Thanks!

gjc5500 Posted January 15, 2010 Share Posted January 15, 2010 The harness comming from the dizzy goes to the box, red from the box goes to + and yellow to the -. the power for the coil has to come from the tach Quote Link to comment Share on other sites More sharing options...
