By “same root cause“ I was not being specific in terms of burnishing points - I just simply meant I would start at the pressure switch. Like Roger I think the compressor can’t generate enough pressure to get the gauge much past the 135 cut-off pressure but I suspect if the switch was operating perfectly and reliably I’ll bet it would reach cut off pressure.<div><br></div><div><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Dec 7, 2021, at 12:20 PM, deanvp <deanvp@att.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><div dir="auto">How do you burnish points that close properly but maybe don't open at the right time?</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><br></div><div id="composer_signature" dir="auto"><div style="font-size:85%;color:#575757" dir="auto">Sent from my Galaxy</div></div><div dir="auto"><br></div><div><br></div><div align="left" dir="auto" style="font-size:100%;color:#000000"><div>-------- Original message --------</div><div>From: Spencer Yost <spencer@rdfarms.com> </div><div>Date: 12/7/21 9:58 AM (GMT-07:00) </div><div>To: Antique Tractor Email Discussion Group <at@lists.antique-tractor.com> </div><div>Subject: Re: [AT] Air compressor failure </div><div><br></div></div>I have the exact opposite problem (but probably same root cause) with my water well pressure switch.
