I called a motor repair shop this morning and was quoted $75 evaluation fee to test the motor. If they are able to fix the motor, they will apply the $75 towards the repair parts and maintenance. Not too bad, but it's a good 40 minute drive to get there.
When I explained to the service technician on the phone that I was getting 1.3 ohms between L1 (Hi Speed) and L2 (COM), he stated that should not be the case and likely that there is a problem with the 'windings', which could not be economically repaired.
So, I am shopping for a motor.
INYOpools has one in stock (cost + tax with FOC shipping) for $596.46.

There is an alternative, but I don't really understand what is different. It cost ~ $100 less.
A.O. Smith Century 2.0 HP Square Flange 56Y Dual Speed Full Rate Motor - B2984 - INYOPools.com
Is there a significant difference (other than cost) to the above two options?
