testing a starter with no load is useles for all except knowing it can spin in free air.
You need a way to load it to spot if it is weak internally.
Hook it all up, get a good heavy wrench and short the two big bolts on the main relay with the big cables on it on the passanger* fenders side, there should be a descent spark and the starter will engage if it's main solenoid is good. If it does engage and spins the engine, then you know it is in the ignition train.
All so ensure the cable to battery conections are good and clean, you are sinking 400 to 700 Amps here at a meer 12V, every bit of resistence hurts you here!
*I put in drivers side, I errored on that!
