Simply connect the two terminals on it with a short wire. This means the O/D will engage/disengage instantly (hopefully) and so you want to treat the O/D like another gear and use the clutch to take the strain off it. Given the cost of rebuilding an O/D, using the clutch when engaging/disengaging is a good thing to do anyhow just to preserve it. It is probably not a popular thing to do, but the throttle switch was disconnected when I bought my BT7 49 years ago. I connected it up once but did not like it and disconnected it again by putting a short loop of wire between the terminals. I just treat the O/D like another gear and use the clutch. Just personal preference.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US'>Regards, Mirek<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;mso-fareast-language:EN-US'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Healeys <healeys-bounces@autox.team.net> <b>On Behalf Of </b>John Spaur via Healeys<br><b>Sent:</b> Sunday, July 2, 2023 10:12 PM<br><b>To:</b> 'Hank Leach' <gradea1@charter.net><br><b>Cc:</b> healeys@autox.team.net<br><b>Subject:</b> Re: [Healeys] Overdrive disengages<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Hank, I have the workshop manuals but the Haynes guide may have something I am missing so please send it.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>I will try resetting the static setting, fine setting it and then the throttle switch<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Thanks!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>John<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Hank Leach [<a href="mailto:gradea1@charter.net">mailto:gradea1@charter.net</a>] <br><b>Sent:</b> Sunday, July 2, 2023 6:49 PM<br><b>To:</b> 'John Spaur' <<a href="mailto:jmsdarch@sbcglobal.net">jmsdarch@sbcglobal.net</a>><br><b>Cc:</b> 'Bob Spidell' <<a href="mailto:bspidell@comcast.net">bspidell@comcast.net</a>>; 'healeys@autox.team.net' <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>><br><b>Subject:</b> RE: [Healeys] Overdrive disengages<o:p></o:p></span></p></div></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>John- it is a .040 feeler gauge that goes under the throttle stop- That is equivalent to about 1/5 throttle opening.

Fine adjustment is made at the arm of the solenoid in which you get it to the maximum lift and then when it drops it clears the base about 1/32" at the same time gently pushing it in toward the casing to make sure it does not bind. Solenoid plunger must drop freely. I can send you that page from Haynes manual if it helps you to set the throttle switch.

When the O/D is actuated there is a parallel circuit that will keep the O/D activated until you press the accelerator pedal, theoretically preventing reverse thrust from damaging the O/D. The parallel circuit runs through the throttle switch on the scuttle (firewall); it sounds like you need to adjust it. It's a simple adjustment using a certain diameter--I don't recall it offhand, but I'll look it up if you need it--drill bit under the throttle stop levers. There's a small shaft off the throttle mechanism that opens this switch--it's just a set of points and a cam inside--with a lever with a pinch clamp. Just loosen the pinch clamp, set the bit under the throttle stop plate and tighten the clamp.<br><br>If you O/D is actuating consistently within a couple seconds or so then your solenoid, operating lever, operating shaft and ball 'valve' are correct. The 'stick-a-drill-bit-through-the-lever-into-the-housing' method is notoriously unreliable; the proper setting is best achieved by measuring the lift--IIRC, it's 1/32" but not sure--of the operating shaft at the top of the O/D hydraulic section.<br><br>Bob<o:p></o:p></span></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>On 7/1/2023 11:55 AM, John Spaur via Healeys wrote:<o:p></o:p></span></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>Hi All,<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US> <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>My overdrive is functioning again after replacing the accumulator housing and piston but it is exhibiting an odd behavior which I believe is related to the adjustment of the setting lever.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US> <o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>When I open the toggle switch, the OD will sometimes disengage immediately instead of waiting until I blip the accelerator.
