booster pump problems

[sunofthebeach]

A few years ago my Polaris booster pump would not run. I hit it with a 2x4 and it started. It ran good for the entire season. At the end of last season, the booster pump quit again. I hit it several times with a 2x4 and nothing happened. I closed my pool not wanting to deal with it. A week or two before my Polaris pump quit my filter pump would not run. There was an issue with the switch not making a connection when I flipped it on. I bent the metal throw switch a little bit and it made the connection and it worked.

I want to verify that my Polaris booster pump is getting electric. The pump spins freely by hand. It does not hum when the power switch is on.

All I need to do is turn on the booster pump and touch my multimeter to the two electric connections going into the pump Correct?

What setting should the multimeter be on?
