Using suitable driver and press, remove bushing(78), if necessary.TESTING1.Using 110 volt test lamp or ohmmeter, test stator(72, Figure 4-11) for ground. Connect one testwire to stator (72) frame and the other test wireto each of three stator (72) wires. Replace stator(72) if lamp lights or meter reading is low.2.Using 110 volt test lamp or ohmmeter, test stator(72) for opens. Perform at least three tests,switching test wires between any two of thestator (72) wires. Replace stator (72) if lampdoes not light or meter reading is high.3.Using test lamp or ohmmeter, test field coil (75,Figure 4-12) for ground. Connect one test wire tofield coil (75) housing and the other to each ofthe field coil (75) wires. Replace field coil (75) iflamp lights or ohmmeter reading is low.4.Using test lamp or ohmmeter, test field coil (75)for opens. Connect both test wires to both fieldcoil (75) wires. Replace field coil (75) if lampdoes not light or meter reading is high.Figure 4-11.Figure 4-12.Go to Sheet 104-13
