just because an alternator is rated 65 amp instead of 42 amp does not mean it always puts out 65 amps! That is the MAX, if your battery is in good shape, you will almost never put out that much unless you leave your lights on for an extended period or something like that. It is safest to not max out any of your gauges though.
