How do you mega ohm a motor 3 phase?
The megger leads are connected in the following manner. Black lead to motor ground terminal or motor frame. The other lead to one of the phase wires. Meg that coil to ground and note the reading. Do the same with the other two motor leads and note the readings. Look at all of the three reading that you have taken. Engineers like the reading to be above 5 meg. Preferred readings about 2 meg. Motor needs looking after below 1 meg.
What is acceptable megger reading for 440volts?
If it is a motor connection that is being tested, engineers like to see it above 5 meg. In reality above 2 meg is fine.
How do you meg a wye delta motor?
To meg (megger test) a wye-delta motor, first ensure the motor is disconnected from the power supply. Connect the megger leads to the motor windings, testing each phase to ground and between the phases while observing the manufacturer's recommended insulation resistance values. If the readings are below acceptable levels (typically 1 MΩ or higher), it indicates insulation breakdown. Lastly, make sure to rotate the motor shaft during testing to ensure all windings are tested effectively.
How do you test an electrical motor to see if is electrically faulty?
There is only two test you can do measure on the Ohm scale the resistance at the power connection if there is a reading then it means it's not open but that's not an indication that the motor is Ok, then measure on the MOhm scale between the body of the motor and any of the power connections if there is a reading then the motor have a internal short, the best is to open the motor and inspect it for black spots on the coils your nose is the best test smell it
A 24v dc motor reads 10 meg-ohms between one of the power terminals and the case of the motor what should be the reading?
That sounds quite good since the main winding should be insulated from the case. 10Mohm is a very large resistance it is well within normal range of the motor.
Can you meg a DC motor?
Yes. You can "Meg" any motor, AC or DC.

What would a 24V DC motor read on a meg ohm tester between on of the power terminals and the case of the motor if the motor is shorted And grounded?
A shorted motor would read zero ohms. Note, however, that a meg ohm tester is not an appropriate test device to assess if the motor is shorted, because the difference between shorted and "operational" can often be just a few ohms - you need a low resistance test device - not a meg ohm tester.
