When I first start up the V10, the 130 amp Ford alternator often spikes to over 14.4X volts and to over 50 amps current flow into the coach batteries if the coach batteries are down a bit from our camping.
An update to my data above: Here at Quartzsite this morning, my alternator's output - with the V10 engine running merely at an idle - spiked to 80 amps for a quick non-solar non-generator one hour recharge of our motorhome's 230 AH AGM battery bank.
I don't know how Ford's 130 amp alternator does this, but some alternator designer(s) sure got it right with this one.
