That needs to be done next. Takes 2 minutes 42 seconds to do.

You should go pick up a voltmeter. They are pretty cheap and a very useful tool to have especially on these renix motors.

The only other way I could think of testing it would be to swap out a known good cps off a renix motor.

For $15 of the cost of a meter, I'd rather test a cPS than replace it.

Unless, of course, you have the ability to "see" electricity.

That all depends on the beverage of choice for that evening.
