It would also require access to the throttle plates, and an estimate of what is "one fifth open". If that is related to the 3/16" rod, then why not just use the rod and adjust until the light goes out? <o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>I have an "overdrive warning" light just above the dash switch that I installed back in the '80s when I didn't mind drilling a new hole in the dash. When the switch is adjusted properly, the light stays on when the dash switch is turned off and then goes off with what seems to me a reasonable movement of the pedal. I would say it isn't necessary to account for slack in the system when using the 3/16" rod.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>Steve Byers</span><span style='color:#002060'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>HBJ8L/36666</span><span style='color:#002060'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>BJ8 Registry</span><span style='color:#002060'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>AHCA Delegate at Large</span><span style='color:#002060'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'>Havelock, NC </span><span style='color:#002060'><o:p></o:p></span></p><p class=MsoNormal><span style='color:#002060'><o:p> </o:p></span></p></div><p class=MsoNormal><span style='font-family:"Comic Sans MS";color:#002060'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> Healeys [mailto:healeys-bounces@autox.team.net] <b>On Behalf Of </b>Bob Spidell<br><b>Sent:</b> Monday, September 04, 2017 1:14 PM<br><b>To:</b> healeys@autox.team.net<br><b>Subject:</b> Re: [Healeys] Overdrive wiring question<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p>I'm working from memory--will check the manual later--but the way I interpreted the instructions were to adjust the switch with the throttles a spec distance--prob. the 3/16" as Steve mentions--opened. For some reason, I thought this should be achieved by pressing on the accelerator pedal to achieve this setting which, of course, would pull up any slack in the Rube Goldberg throttle mechanism. So, I set it this way but felt that it required too much pedal when disengaging the OD. I just fiddled with the adjustment to where the OD disengaged with what I felt was appropriate pedal. Maybe the 3/16" should be measured without allowing for linkage slack, maybe not; does anyone know for sure?<o:p></o:p></p><p>Bob<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
