Greg SmileZ Posted January 20, 2004 Share Posted January 20, 2004 Search does not seem to work....so I've posted this. I've seen lots of discussion (on zcar.com) regarding a tach not being stable, jumping all over the place. SBC with stock HEI and I've hooked mine up per JTR and installed the resistor. Has anyone else had this problem, and if so what is the solution? Thanks, Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted January 21, 2004 Share Posted January 21, 2004 What kind of Z? I thought I remember the JTR book saying that a 240 tach would not work no matter what, I may be wrong. Quote Link to comment Share on other sites More sharing options...
Greg SmileZ Posted January 21, 2004 Author Share Posted January 21, 2004 1977 280Z...followed JTR instructions, and is still jumping around. Thanks - Greg Quote Link to comment Share on other sites More sharing options...
BillZ260 Posted January 22, 2004 Share Posted January 22, 2004 looking at my z haynes book, the tack is directly connected to the ignition swtich. May look at another "hot" source for the tack. Quote Link to comment Share on other sites More sharing options...
