Here we go again, trying to keep this 1998 Neptune washer a washin. However in order to do so, please assist in the following diagnosis: Several weeks ago, machine stopped during the rinse cycle. No big deal, pushed the start button and it would finish the cycle. That was fine until pressed the start button, it smoked and tripped the breaker. I purchased a new start button and thought all would be good but button smoked again. I have completed the following: Motor test, replaced the control board and wax motor on the door lock (just because I had these on hand). Did Ohm checks via the timer plug and found the pump motor to be excessive high: 72.6K rather then the specified 18. Checked the pump motor directly (with wires disconnected and it was within spec. Problem seems to be in the harness? Or elsewhere? Any recommendations on where to fix what?

I would definitely inspect the molex connectors for signs of overheating, as your failure seems to be the result of excessive current. The push to start relay switches 120V to the timer and the motor controller board, so I would follow that path and see if you have the same type of high-resistance situation you found in the pump wiring...

There is a tech bulletin from Maytag about burnt resistors on the control due to loose connections and/or failed components:  TDL-0052A-B. I am unable to upload it for you, but perhaps one of the High Karate members can find it in the Samurai tech sheet stash...
