Default Alternator on or off the motor when it goes on the dyno

Just wondering, i have to remake parts of my bracket, the alternator doesnt clear the front of the IA block with the bracket in its current configuration. So should i have the alternator on when it goes on the dyno? Ive seen a few of Kauffmans post on FB and there is not alt. On the motors.

We dynod my 540 with the alternator on it. It wasn't charging a battery, but it showed that the belt would stay on at 8k plus.

Can be off. Dyno will supply power
