haha ok correct me if im wrong but dont a split charge system charge the starter battery first and then the winch/leisure battery? and it wont let the winch use up the starter battery? so then he has the same problem of an empty winch battery if he keeps his alternator.

But ye redhands right do check ur existing alternator output.

Anyone using a electric winch is going to have the problem of flat batteries if winches for more than couple of minutes. even an 100amp alternator won't keep up with a winch on full draw. Yu can get round it by using snatch blocks. which reduces the strain on the winch and the drain on the battery.

I stand corrected! anyone got an idea why his engine cut out tho?
 
Does it involve;

A. A Grinder with assorted cutting discs
B. An assortment hammers
C. Blow torch
D. Non of the above.

If D is correct I cant do it!:D

i have 2 numax batteries,an all makes 4x4 100amp alternator and a tmaxx digital split charge system..

i compete in winch challenges and the warn xd9000i winch certainly gets used for more than a couple of mins at a time.

ive never experienced any probs with flat batteries,but a snatch block is used at every opportunity.

with the tmaxx split charge system you can only control the power to the winch by taking draw from both batteries if needed.

as i said very early on check the output from the alternator
both the volt meters i have connected to each battery are indicating 14.7v....

Thanks for the help lads, I will get the alternator checked today if I can, then I will let you know what the reading is. Thanks again.
 
I would say his diesel cut out because he flatened the battery that much the solenoid wouldn't stay open to allow diesel through.
Ive gone for 2 batterys and a split charge system. Second battery only supplies winch. So far ok but I agree with above, snatch block as standard will really help preserve battery and winch.
 
Was reading through the whole thread just wondering how long it was going to take somebody to work out the solenoid thing :D :D :D

Its bloddy obvious if you run it completly flat then its going to cut out, as the solenoid closes and the fuel stops. - If its a petrol engine then a flat battery = non energised coil/fuel injection system and again engine stops

The simple answer to your question is that you are not going to find an alt that will keep up with your winch when pulling for a long time(look at the size of the cable comming from your alt!). An electric winch is designed to get you a couple of feet out of a ditch etc. NOT for hauling long distances. - thats what an engine is for - use a rope and use the low range and drive!!!!!!!!!!!!!!!

If you need to haul with a winch the ONLY option is a Power Take Off winch using hydrolics, or to get a huge battery bank (I would suggest a seperate system from the starter motor, and if your going to haul with it then use DEEP CYCLE batteries as a cranking battery is only designed to supply this sort of current for a short period and not to be run flat - BOSCH make some nice ones but are bladdy expensive mind you. You will then need to leave the engine running for a few hours/ get a LARGE charger and leave it on charge for a few days!

i totally disagree with your theory

when i compete in winch challenges your 9 times out of ten in confined spaces generally in wooded sections/water/steep banks

the winch is used alot hence why its called a winch challenge
you have to winch sideways sometimes to get you to the next punch
at no time is a rope used to recover your position its impossible

you say that we wont be able to find an alternator that will keep up?
my 100amp seems to cope fine

in competition my winch/alternator have never failed.

i dont know where you get your opinion that an electric winch is only to be used for a couple of feet?
 
It depends what type of winch you have, the current it draws (which depends a lot on the gearing it has inside it) and what you use it for.

What i was trying to say was that there were better ways of pulling a landy up a 100ft hill than sitting at the top winding away with your winch.

Obviously if your doing 'winch chalenges' then you probably have a decently geared winch, proper cables, and a system designed for it.

A 100 amp alt will only output 100amps into a flat battery, and is not designed for constant use supply 100amps for hours on end.

As i only use things like this for getting myself out of difficut situations (e.g. out of a load of snow up the side of a cumbrian mountain) and not on some made up challenges, i obviously have diffferent kit, and i guess the author of the thread has the same.

Either way if you are pulling hard for a long time, the alt will never keep up with the winch, and eventualy whatever you are doing will run the battery down. I bet yor chalenges dont call for CONSTANT winching like pulling up a 100ft slope, and i bet you switch it off for a few seconds between use, giving it time to do some charging?????

Either way - i bet i was right about the solenoid!
