1. TR7 to V-8 Tach modification (score: 1): Author: Perry Robinson <PROBINSO@flower-mound.com>; Date: Thu, 25 Mar 1999 13:13:39 -0600; Does anyone know how to convert a TR7 tach to work with a v8? I have read several books on Z-car/V-8 conversions, which state that a simple resistor (of the proper size) is inserted into the wire dri; /html/buick-rover-v8/1999-03/msg00030.html (7,761 bytes)
2. Re: TR7 to V-8 Tach modification (score: 1): Author: "The Becketts" <hillman@bigpond.com>; Date: Fri, 26 Mar 1999 18:50:33 +1000; Sounds very unlikely. Fitting a resistor will merely reduce the voltage and/or current to the tacho. Some Smiths tachos use a current loop through an inductive pickup (e.g., like the one in my Hillm; /html/buick-rover-v8/1999-03/msg00048.html (8,656 bytes)
3. Re: TR7 to V-8 Tach modification (score: 1): Author: Bob Wilson <emrmicro@cadvision.com>; Date: Fri, 26 Mar 1999 15:07:23 -0700; Some time ago there was a similar question on the MGB V8 BBS. One fellow who put a Buick into a MGB came up with an electronic buffer to divide the V8 ignition coil pulses by two - "fooling" the Smit; /html/buick-rover-v8/1999-03/msg00050.html (7,999 bytes)
4. RE: TR7 to V-8 Tach modification (score: 1): Author: Perry Robinson <PROBINSO@flower-mound.com>; Date: Fri, 26 Mar 1999 16:43:30 -0600; Thanks for responding. I understand what you are saying. Is it that most "modern" tachometers use a different type of circuitry that measures the pulses from (or to) the ignition coil, and then conv; /html/buick-rover-v8/1999-03/msg00051.html (10,267 bytes)

6. RE: TR7 to V-8 Tach modification (score: 1): Author: Randall Young <randallyoung@earthlink.net>; Date: Fri, 26 Mar 1999 15:41:22 -0800; Many tachs can be switched to/from 4/6/8 by changing a resistor, but it's not usually in series with the connection to the coil. For analog tachs, there is a simple circuit inside that converts the; /html/buick-rover-v8/1999-03/msg00054.html (9,168 bytes)
7. Re: TR7 to V-8 Tach modification (score: 1): Author: "perry robinson" <tps@fastlane.net>; Date: Fri, 26 Mar 1999 18:42:26 -0600; Randall, that is exactly what I believed to be true about how tachs actually convert the "signal"going to them into linear movement!! I believed that is was voltage, not "frequency" that actually dro; /html/buick-rover-v8/1999-03/msg00056.html (10,182 bytes)

Re: TR7 to V-8 Tach modification (score: 1): Author: Mark Tinker <mtinker@cisco.com>; Date: Sat, 27 Mar 1999 21:19:49 -0600; I found the following info. on the Listquest server from 1997: I have the schematic for the TR7/8 tachometer. I have used it to re-calibrate several TR7 tachs for TR8 use and to modify the tach for u; /html/buick-rover-v8/1999-03/msg00061.html (12,495 bytes)
