The Transistor is bad/shorted,Test the TIP36 Transistor on the PPB board and also test the driving TIP102 on the CPU board that connects to this TIP36.It's always recommended to test both the TIP36 on the PPB board and TIP102 on the CPU board.MM set on diode setting,Red probe on metal tab and black probe testing legs.A .4 or .6 reading should be seen.
Quoted from Gexchange:new coil and Transistor. Do em in pairs
That's correct,Change them all out at the same time.
