Testing for short to ground Using Ohm meter: Disconnect all power from machine. Check all three wires singly T1,T2,T3 (all three phases) to the ground wire. Readings should be infinite. If its zero or reads any continuity at all, then a problem exists with either the motor or cable ...
If the wire terminals and wires are coated ( not bare metal) you can use a pair of needle nose pliers with insulated handles to short/discharge across the capacitor. Set your needle meter to an OHM scale, Example: Rx1 Touch your leads together and 0 ( zero ) out your meter with the ...
The meter usually read around 80-200ohms. If its less then 20 ohms coil is most likely shorted. If its above 500 ohms it is most likely open and should be replaced. If possible look for another solenoid to compare readings with. If coil ohm resistance looks ok and correct voltage is at...
