Hey I was wondering if a brand new alternator (60 amps) could handle my electric fan. It is a Taurus unit and I do not have a multimeter to check voltage across the terminals. I was just wondering if anyone thinks it would handle it. Thanks

Probably not. Keep in mind that he 60 amps is probably at ~2500 RPMs. You'll need 30 amps for the fan alone, and you'll need that at idle. Turn on your lights, stereo and heater in the winter time at idle, and you're looking around 45-50 amps minimum. I'd recommend a 100 amp or better.

More is better, that's for sure. I have a fan which draws 40 amps at start-up and runs at 20 and I'm using a 55-amp alt., but currently I don't have a/c. When that goes in, also going in will be a big-ass alt!
