Before you even get the meter out do a quick check and manually operate the S Relay to see if it locks in and starts the motor. If it does lock in then you have easily proved:

1. There is power
2. Fuse
3. Bounce switch
4. The Anti-cheat switch and Motor 2B switch is good.
5. The S coil is good

and that takes all of 1 second

I rarely use a meter on an EM...using a jumper to bypass switches and manually operating relays is much more efficient.

Be aware that most multi-meter continuity checks will beep when the resistance is below a certain threshold (e.g. IRC 40 ohms for some Flukes) so you have to be careful that you are not checking continuity back through the transformer winding. Measure ohms as MarkG suggested.

Pic below shows the switches that operate the motor. First check to see which of the relays is pulled in. If no relays are obviously operated then you will have to check the individual switches.
