To load test the alternator I disconnect the ignition.
Crank for a good 30-45 sec.
Connect ign and start.
With a clamp style amp meter you will get a reasonable idea.
On start up amps will be high and volts low.
Run at 1500 rpm as volts go up amps will drop.
If you have an amp meter in the car you wont need test meter.
