I have checked the wire and it does not feel as though it is getting overly warm. To avoid the lose connections in the future, I am going to use a soldering gun and be done with it.

thanks guys as always,

I'd say the solder is a good idea, that is a high current circuit, and the connections HAVE to be really good !!

As far as checking the motor with the meter, you can check continuity, and that might tell you if a winding is open (extremely high resistance), but motor windings normally have almost no resistance, so it will only read 2 or 3 ohms even when everything is good, so unless you're using a good meter and it's reading .0000 ohms, it's gonna be tricky to tell normal motor windings from shorted motor windings.
You should be able to tell if the controller is putting out by measuring voltage right at the motor. If you know the controller should be on, then you can put the meter on DC voltage and you should read close to Battery voltage right at the motor.
