Motor will not start (pics)

Thanks guys

I have tested the batteries with a tool like that, both tested ok, I even try with my truck’s battery to double check…
Is the starter motor supposed to be resistant if one turns its gear by hand? Also, for the fact that it would not crank by turning the ignition key, I believe the starter motor and its solenoid could be the culprit. Tomorrow I’m going to investigate further, perhaps take the starter apart before ordering a new one. Thanks again for your help.
