Testing a starter motor

Engine is rebuilt after my, ahem, clever driving through a river plan

I think my starter motor is toast.

I’ve checked it my connecting it to a car battery with jump leads then used a power supply to the solenoid. The solenoid clicks and the toothed wheel tries to
Move but doesn’t.

****ed right? Or have I not set it up right?

Connect the jumper to the main feed to the starter,missing out the solinoid this should turn the starter. If that works it’s the solinoid that need pulling apart & freeing up.

Chances are something has seized together after the swim.
