The job prints we have didnt show any of the NSP connection so my guys couldnt tell where things went. So when we got prints that showed NSP connections we were better off. E-man shindler has changer that resistor from 1K ohm to a 10 ohm???? Also why it is opening stays a mystery. We disconnected the starter coil so everthing was passing thru the resistor and it didnt even get warm???? We replaced the coil and added surge protection but time will tell 1 week or 1 year who knows. When Adams tec support finally answered they said the same resistor had been opening when Otis had the job. They are checking to see how many of the 75 boards they sold last year had the same problem...
