He was very vague. He said the fan usually draws around 25-30 amps. The fan isn't the only thing drawing amperage. Ignition system, lights, blower motor radio and on and on. When I said full load that's what I meant. That's the only way to make a fair comparison. When I load test an alternator for a customer, it will pull the idle down a few hundred RPM. That's a load. That's what I am talking about.
