    Try replacing the sweep run and sweep reverse switches in the back end control box. Replace the sweep reverse first.

      Tried sweep switches no help. Checked capacitor resistance was 1249 think it is originally 1250 right? Motor gets super hot in 5 min then trips. Also has a deep buzz when sweep runs. I have 120v at plug.

        sounds like an issue with the start winding wiring. Did you try a good working solid state?

          Kind of sounds like the plug is wired up incorrectly or that you have a loose or broken wire in the insulation. Did you change the cable or just the plug? Compare the wiring to the next machine over.

            Replaced plug. Also double checked the plug wiring. All is good as far as I can tell. The voltage is 120 at plug. Running Westinghouse combo motors.

              P.s. It only takes about 5 min before it heats up and trips.

                Check linkages and sweep shaft bearings for binding.

                  Linkage and bearings are good. Disconnected arm and moved sweep manually. No binding.

                    Update. First off thanks to everyone that helped. Much appreciated. The thing that really helped was you said to replace things with ones you know work. I have read it many times before but for some reason it stuck with me today. Thanks again
                    so I swapped the table and sweep solid state starter. The table over heated. Bingo! Lesson learned hopefully not forgotten. Crazy thing is one was new.

                      Glad you got it figured out.

                        That is why I like to keep my motors OEM. I really do not like the SS switches.
