Installed Pertronix in 2002 and did nothing with the tach. It ran perfectly till 2017 when started reading erratically. That is when I sent it off to Nisonger who rebuilt to work with points OR Pertronix neg grnd. It was just wore out and proved to be worth the cost of repair.</p><p class=MsoNormal> <a href="http://www.nisonger.com/">http://www.nisonger.com/</a></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>WD 67BJ8 190,000+miles</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986">Mail</a> for Windows 10</p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:healeys@autox.team.net">Fred Wescoe via Healeys</a><br><b>Sent: </b>Friday, November 27, 2020 11:09 AM<br><b>To: </b><a href="mailto:Healeys@autox.team.net">healeys</a><br><b>Subject: </b>[Healeys] Tach question</p></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Listers,</p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>A few days ago, on one of the lists, there was discussion of a 66 BJ8 electronic tach that was not reading correctly after installing a Pertronix ignition setup. I just installed the Pertronix (points conversion) system and coil and now the tach does not read correctly. The comments mentioned that tachs had to be rebuilt specifically for the pertonics conversion. Several places that repair/rebuild/calibrate our Smiths tachometer with the Pertronix ignition system were recommended. As I put the car away for winter, I would like to get the tach repaired/rebuilt/calibrated. I have lost those comments and therefore the links to those repair sources. Can anyone refer me to those services? </p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Thanks as always for the comments and wisdom,</p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Fred</p></div></div><p class=MsoNormal>66 BJ8</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
