Just about as long as it will with the engine running. It's all battery when you use a winch, the alternator just re-charges the battery. With a 4000 load a 12V 8274 will be using 275 amps. A stock FJ40 alternator puts out 45 amps IIRC.Steve C said:How long will an electric winch run with the motor off?

Lot of good that PTO is going to do.
As an example of a situation where an electric winch would be better I think it worked.lowenbrau said:Right! Its way too far off camber for a carbureted gasser to run. If it was a BJ40 he'd have no problems with a PTO.
Seriously, even a Jeep should run in that amount of water.
