So I need a little more edumacation.

I went to buy a test light and after discussing what I was doing with the hardware store guy he said I needed a continuity tester. After getting home and reading about how the tester works I'm confused. I have a hard time conceptualizing electrical problems so let me explain how I was thinking about the problem and then you can explain the error of my ways.

In testing the wiper motor I thought the idea was to see if power is going to the motor when the wipers are switched on. There are then two possibilities:
A - Power is getting to the motor - this would indicate the motor is not working.
B - Power is not getting to the motor - this would indicate that something else is at fault and really give me no information about the motor.

The continuity tester doesn't look for existing power but rather creates its own to look for a complete circuit. How does this help me? If there is a complete circuit through the motor does that mean that the motor should work? Or did I buy the wrong kind of tester?

Also there are several wires to the motor - which ones do I test? The red/white wire comes from the fuse and brown goes to the ground - are these the wires to test?

Thanks
