The only way that the alternator would see a "dead short" is if there was an actual short. The winch will pull the battery voltage down to 9Volts on a long hard pull.............................................. .................................................. ......................... .

After years of 4wheeling and winching I have never burned out an alternator from running my truck while using the winch.
Running a bigger battery is a must with a winch, smaller batterys go dead too quickly.

Well, after reading all this I have come to only one alternator has outlasted the winch running it the way I have been running it. The winch just quit but the alternator is still doing it's job. I was also killing batteries, but last summer I threw a Crappy Tire Spiro-cell battery in there and it has lasted.

When ever you put a new alt in a vehicle,the instructions it comes with say, if the battery is not fully charged, the warranty is void. GM alts are the worst for dying from being overworked. I love watching people winch and rev the engine, with smoke pouring from the alt. And you know for a fact that all electrical things actually work of smoke, and the battery is just a storage unit for said smoke. When all the smoke leeks out a starter, alt, or wiring, that unit ceases to work till you fix, or replace it, and connect it to a good source of smoke. What you have said is correct for the most part in theory, but in practice, theory may leave you with a stuck truck and a dead battery, and once the voltage drops bellow 9 volts most vehicles will stop running.

I think the key thing to remember is to take it easy... don't be afraid to stop and let the winch/alt rest for a minute or 2. Winching to the point where your battery is down to 9V is just silly.

But at the same time, we all know working something hard wears it out faster.... yet we all mat the skinny pedal.

"Let the smoke out". My instructors used that phrase all the time
