Michael Posted November 5, 2000 Share Posted November 5, 2000 Is there a clever trick to successful connection of the stock 280Z tachometer to an HEI distributer? The ubiquitous JTR book mentions the connection of two wires from the ignition module in the passenger's footwell: (1) the blue wire going to the "tach" terminal (with a resistor in series) and the black-white wire going to the "bat" terminal. But that's with the ignition module removed! It seems to me that the blue wire would then be connected to nothing. I've starting the rewiring of my electrical system from scratch. The ignition works, as do most of the lights. Now I have a bare ’78 280Z tachometer that I’m trying to connect. Evidently, only two wires are necessary for the tachometer to work: ground, and the connection between the tachometer receiver (green wire) and "tach" on the distributer. Done that way, the needle might bounce around, or be otherwise inaccurate, but at least there should be SOME signal. But I get no signal! Am I missing something, or does my tachometer have an internal problem? Quote Link to comment Share on other sites More sharing options...
Guest dragon Posted July 30, 2006 Share Posted July 30, 2006 install a 15k resistor between distributer and tach then fine tune tach thru the small hole in tach.be very carefull,do not over tighten trim pot will break !! Quote Link to comment Share on other sites More sharing options...

gvincent Posted March 30, 2010 Share Posted March 30, 2010 Now if we could only get the pictures back to all those great old posts, many a time I am reading a very informative old post only to have no pictures attached to the posts anymore, and some were stickies.
