I see you're still waitng for an answer......Preset the meter to 600v (A/C) first; hold both prongs on the places described below at the same time, look at the meter and it will show the voltage you have to the motor.
To check the voltage/current with a volt meter, touch the Red (wired) prong from the meter to the Black or red wire terminal on the motor connection, where you connected the wire(s) to; then touch the Black wire from the meter to the White wire on the motor connection. If you're only getting about 120v, then you do not have 240v, and the motor you have will not work, unless you have 220/240 supplied to the motor, assuming the motor cannot be reset to accept 120v.
Another way you can test the voltage is to touch the Red prong from the meter to the Black wire connection on back of the motor, and touch the ground (green) lug where your ground wire should be attached, it should read about 120v, then move the Red prong to the White wired connection while still keeping the Black prong on Ground, if you also get 120v there as well, you have 240v, if you get nothing on the White wired connection at the motor, you only have 120v going to the motor.
