I should say that a typical starter for a V8 doesn't usually draw 400
amperes, though a high-compression V8 used in racing might cause it to 'momentarily' draw upwards of that amount. Not germain to the discussion at hand anyway.

And why are your winch cables larger than your starter's?

Bill, you really should stay out of electrical discussions since you
don't have the background to participate other than as an unarmed man would in a gunfight. To humor you, the reason some winches may have larger cables than some starters is that a winch circuit is designed for longer duty cycles and thus the cables may be required to carry that kind of a load for longer periods of time than a starter motor would need.

Amazing, and it does all that without using any more amps.

Bill, for the new warn 9500 winch, the specs are 160 amps for a 2000 lb
pull. That would be like pulling my CJ7 straight up a cliff. We were talking stalled in water here. So if I just have to pull it on wheels out of the water, the rolling weight is closer to 200 lb or 300 lb, maybe 500 lb with some rocks in the way. (I mean it only takes one or two people to push a Jeep right) This will draw more like 100 or less amps. I think my Optima battery could handle getting me out of the water using the winch. I 'know' 100% for sure my Optima battery can get me out of the water using my starter and 2nd gear to walk it and still start the Jeep a bit later. Now if you need the 'full' 9500 lb pulling to get out which will draw 450 amps, you are in deep do do with a stalled engine unless you only need a 1' pop out.

Bill is getting a fair education on 'lectrical stuff today.

BUT, for the sake of argument what would it take to generate the
power required to max it out at ninety five hundred pounds.

Pretty much any battery will handle a 450 amp load for a short time. My
alternator is only 70A or so. I have had my cables smoking once when it stalled pulling a wheel and axle less hulk out of the bush. That was a serious draw and the battery/alternator had to work hard for a while after. It pulled the idle down for a while because of the draw on the alternator. I had to use my hand throttle.

Hi Mike,
FYI Warn battery recommends a "battery with a minimum rating of 650 cold cranking amps is recommended to obtain peak performance from your winch.": http://www.jonfund.com/technical/tec.../winchtech.pdf God Bless America, ßill O|||||||O http://www.billhughes.com/ Mike Romain wrote: > > Pretty much any battery will handle a 450 amp load for a short time.

TRANSLATION --> "easy pulls". jery ive stated many times that electric winches do fine most of the time. the benefits of going hydraulic (and ive said this many times) become obvious when you need a winch the most....on long nasty tough pulls. for most situations an electric winch will serve you just fine, ive _never_ said otherwise. hell, in _most_ situations a come-along will serve you just fine. while it also handles easy pulls, the hydraulic winch is designed and built for true heavy duty/industrial usage and this is where youll benefit from them most. |
