You need to first find out what the motor is doing with regards to OL. I am assuming single phase so read the OL setting and understand the type of starter used.
Put clamp meter on the motor circuit and read current reading to see if it is showing a small increase or high load current.
Check out motor to see if you have staled or locked rotor.Also the OL block in the starter should be set at motor running current
When you have collated the info you can then use your insulation tester to check out the Motor.
I have found over the years always best to fit a new OL block in the starter but depends on the starter.
