the linear style winches draw around 300+/- at full pull. the 100 amp will do it a lone if its running. you will never be able to completely keep up but the duals will go a long way when the motor wont run.

i ran a 1000 cc/amp battery and a 100 amp alt and never ran short of power [ 8274 pull upwards of 400 amp at full pull]. optimas are 800 ish cc/amp but they will last longer with the motor stoped than a standard battery.

that's pretty much the answer right there. Will you theoretically be able to winch all day long under full load? no, but even if you had the power capabilities you winch would overheat anyway. Will that be enough to be able to winch ourself or someone else when needed, yeah as long as you don't overheat your winch.

 

Thanks for the replies, I thought I read somewhere that they pulled around that much but I was not sure. I talked to the guy at the alt. shop and he said around 40-50 amps and I thought that sounded low, maybe that is with no load.

 

go to warns web site look for specs it will give you amp draw at load and layer for your winch

Go to MileMarker and get their CD

There you will see actual pulls , to fracture of the cable or stall, and with an amp meter attached.
You can reach 400amps when the motors heat up.

sorry to thread hi jack

i have a mile marker 8000. i installed a 85 amp started-type selenoid to turn the winch on and off.... so will my selenoid not work?? should i wire it back up how it all came??
