Also verify they are about the same (within a couple of percent). If its way out of this range, stop here.</div><div><br></div><div>If they think they've gotten at least 5000 run hours, I'd stop here. These air cooled machines can last longer if well taken care of, but that is the design life. I have a few Kohler air-cooled with >5000 run hours so it can happen.</div><div><br></div><div>I'm a fan of checking the integrity of the alternator/rotor with an excitation test but you may be limited in what is possible with a cooked controller. You can ask me direct for more details on this. Probably the controller is cooked and that's it, but I have had lightning to more things to generators.</div><div><br></div><div>I would try the parts for techs but here in Colorado you can also call Power systems West in Aurora. They will need make, model, serial number and they can price out the part for you. This will at least get you a best case price for replacing the controller. You can't rely on interchangeability of these controllers. There are often changes that need harness modifications. </div><div><br></div><div>Good luck</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Oct 23, 2023 at 4:48 PM Dana Orzel via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><div lang="EN-US"><div><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif"><a href="https://www.partsfortechs.com/" target="_blank" rel="noreferrer">https://www.partsfortechs.com/</a><u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif">These guys sold me an automatic volt regulator for my 20KW Onan for ¼ of the price that Onan wanted SUPER helpful, not sure if they can help you but reasonable, knowledgeable, & friendly, & They saved my bucket.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:"Century Gothic",sans-serif">___________________________________________________<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:"Century Gothic",sans-serif;color:rgb(56,86,35)">Dana Orzel c- 2087217003 e – <a href="mailto:dana@solarwork.com" target="_blank" rel="noreferrer">dana@solarwork.com</a><u></u><u></u></span></p><p class="MsoNormal"><u></u> <u></u></p></div></div>_______________________________________________<br>
