separate them use an isolator (best) or a solenoid (good) if you use an isolator make sure its rated current handling exceeds the output of the alternator and if useing a solenoid make sure it's constant duty

Should also check that your alternator has enough output to run the winch(high amperage draw), I would also check your ground and or winch wires for corrosion, loosness or perhaps too small positive or negative wire size.[cheers]

no alternator will ever have the output to run a winch.

at full pull a winch can draw 300+ amps. The largest alt i have seen is only 150ish. Most stock ones are 75-100amps.

Winching relies almost entirely on your battery. The alternator will add a small amount of time before it goes dead, but not enough to make much of a difference.

By the time you battery goes dead you winch probably needs to cool down anyways, so stop for 15mins and let you bettery charge up before winching again.

good... i would feel guilty if he owned my old pickup.

good to have another toyota on board though

he's got stereo, lights, winch etc. so dual set up would be good.

12voltguy off pirate has this kit where it seperates the two batteries and you use 1 battery solely has an ermgency battery when your primary is dead.

what i dont like bout this is you're still only using 1 battery to power your winch, when two is a lot better. You're going to need that 2nd seperate battery only cause you drained the primary because it wasn't in parellel with a second battery. Hope that makes sense, but thats my opinion.

I guess anyway you cut it, two batteries are a lot better than a single one.

painless makes a kit not that cheep tho but simple as hell to installp/n#40102

a good alternator and a single healthy battery usually has no problems keeping up with normal winching. your wire hook-ups for the winch and good connection are also very important. for dual setup I prefer two identical batteries with no isolator.


not sure what alternator you have right now but I do have a nice very low mile one from a 89 full load 4runner. paid mucho dollar for it a while back but you can have it for a good deal derrick if you need it.

the only problem with running 2 batteries is you put more of a work load on your alternator and they will burn out quicker.

There is a guy on ebay that remans alts and has a 150 amp alt for toys. good price too at under $300,


DOnt they use a ford starter solenoid for a 2 batterie setup?

its not a ford starter solinoid but similar rated for continuous duty

What I have is dual batteries and I run two wraps of cable. Full drum of cable draws a crap load more than partial. For long tugs I have more cable in the back but I don't use it very often.

I use to run those larger ones .....MR SPARKS in Maple Ridge carries them

I run dual batteries using a solenoid to isolate them. my "primary" battery is a marine deep cycle...which powers everything on the truck including my rear winch. My "secondary" battery is a normal starting battery which is isolated through a solenoid in a manner that only connects it (in parallel) when the ignition key is turned on. My theory is that I can run the primary completely flat as often as I want -- and when I turn the key on the secondary effectively jump starts the primary. When the engine is running, both are charging in parallel. I'm sure there are problems with this in a theoretical sense, but it has worked well for me for the last 4 years....and it's almost impossible for me to kill my battery reserve to a point that I can't start the truck.

How bout 2-3 alternators run in series?!! Is your wench a 24 volter perhaps? All b.s. aside; I run a single Optima red top with my stock Toyodi alternator(87 22-R powered pick-up) which powers my Warn 8274 fine; if the controller works that day!! I'd imagine my power maker is only around 80 amps(?) it;s too dirty to see any numbres'.[cheers]

Personally I think the isolators are a waste of money when you can buy a constant duty solenoid for $25.
