This will verify if the cable, splices and motor windings are OK. But, it won\u2019t tell you if there is a mechanical issue. I may be able to help you directly, or else refer you to a solution. I\u2019ll write to you off-list if you don\u2019t mind.</div><div class=""><br class=""></div><div class="">As an aside, if I may put on my educator hat: The industry uses the term 3-phase to refer to conventional 3-ph AC pumps. Your helical rotor pump, we refer to as \u201cbrushless DC\u201d or the better, but less common term \u201celectronically commutated motor (ECM)\u201d. It does use a form of 3-ph, via 3 wires, but we name it something more specific to distinguish it from the conventional AC.</div><div class=""><br class=""></div><div class="">\u2014 Windy</div><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Sep 21, 2018, at 1:10 PM, <a href="mailto:re-wrenches-request@lists.re-wrenches.org" class="">re-wrenches-request@lists.re-wrenches.org</a> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 0px;" class=""><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif; color: rgb(127, 127, 127);" class=""><b class="">From:<span class="Apple-converted-space"> </span></b></span><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif;" class="">John Blittersdorf <<a href="mailto:john.blittersdorf@gmail.com" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">john.blittersdorf@gmail.com</a>><br class=""></span></div><div style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 0px;" class=""><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif; color: rgb(127, 127, 127);" class=""><b class="">Subject:<span class="Apple-converted-space"> </span></b></span><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif;" class=""><b class="">Re: [RE-wrenches] High Volume Solar Pumping</b><br class=""></span></div><div style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 0px;" class=""><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif; color: rgb(127, 127, 127);" class=""><b class="">Date:<span class="Apple-converted-space"> </span></b></span><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif;" class="">September 21, 2018 at 6:28:50 AM MDT<br class=""></span></div><div style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 0px;" class=""><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif; color: rgb(127, 127, 127);" class=""><b class="">To:<span class="Apple-converted-space"> </span></b></span><span style="font-family: -webkit-system-font, "Helvetica Neue", Helvetica, sans-serif;" class="">RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">re-wrenches@lists.re-wrenches.org</a>><br class=""></span></div><br style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><br style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class=""><div dir="ltr" style="caret-color: rgb(0, 0, 0); font-family: ArialMT; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class="">Hi Windy,<div class=""> I have a question about 3 phase pumps but slightly off topic for this thread. I have a Lorentz pump I bought from you 18 years ago and is at 480 feet and my well will only</div><div class="">give me 1 gpm with occasional air coming up . I replaced the control board 3 years ago and it had been working fine. It quit a few months ago right when we were getting into a drought here in Vermont. How can I be sure it is a controller issue and not the pump itself. My spring has dried up and I am now pumping from my other building and another spring 800' away using a Shurflow 12v pump. It is not doing well. You mentioned a Lorentz distributor which triggered me to jump in here. Is there a way to determine if the pump is good with resistance test of each leg? Or leg to leg with wires disconnected from controller? </div><div class=""><br class=""></div><div class="">John Blittersdorf</div><div class="">CV Wind Service (and Solar)</div></div></div></blockquote></div><br class=""></body></html>
