The Ford Barn

Good evening all in the Brain Trust. My '31 stock(mostly) truck developed a hole in the radiator, on a hot day. Noticed steam coming out the radiator cap and the overflow tube, towards the ground. The Boyce temperature gauge needle started dropping(no water to measure?) and the ammeter started showing an increase in charge (10 amps) with no lights on. I am using a '57 Ford, 2 brush generator with a voltage regulator hidden up under the gas tank, on the inside of the firewall. This setup has worked well for years. Why did the ammeter charge rate go up significantly with the overheated engine??? Thanks for your ideas!
