Fun, when you say " The battery still had 11.5 volts enough to start the engine"
I would say that was NOT a battery stabilized and at rest IE it was too soon after receiving that high charge.
FYI A "good" flooded lead acid battery AT REST AND STABILIZED FULLY CHARGED AT 77 DEGREES SHOULD READ 12.63 VOLTS....If its ONLY 12.5+ volts it's partly discharged. NOTE if your voltmeter isn't accurate that's your problem, below are correct voltages.
Those abnormal high voltages may be because the voltage regulators VOLTAGE SENSING CIRCUITRY isn't connected to monitor correct battery voltage so its running wide open or else its toast or simply not wired.
A possible short somewhere in the regulation or charging circuit could cause a high current draw. Maybe a short is overloading the alternator and all the current isn't getting to the battery itself??
I suppose some battery problems could possibly cause a high current draw, I would take the battery to a shop for a proper LOAD and voltage and specific gravity test to insure battery condition BEFORE SMOKING MORE ALTERNATORS.
Is this is three wire or a so called "one wire" alternator as it doesn't appear to be sensing battery voltage correctly. It may not be wired correct !!!!!!!!!!

Today's Featured Article - Tuning-Up Your Tractor: Secondary Ignition Wires and Distributor - by Curtis Von Fange. In our last episode we spent the entire day checking out the spark plugs. Is that efficency? Actually, it took more time to explain than it really did to do the inspection. At any rate we decided that a compression test was in order so we could verify the internal engine status. That way we wouldn't buy any tune up parts until we were sure that the engine was in reasonable mechanical condition. Our tests showed a fictional compression reading of 85, 80, 82 and 86 psi. That is well within a
