winch on dual battery system
Hello there .
My question is, to use the Aux battery or the car battery for my Warn 9000 winch?

Cranker mate. All other accessories to the second battery but winch to the starter. Your alternator will kick in as soon as you start winching.
Its a Nissan! =====> Its a Keeper!! ....... Got a TD42 in it BONUS!!
....... I'm a lucky bugger! I've got 2 of em!

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

Good rule of thumb with dual batteries where any type of isolator or charger is involved;
-If it is an accessory that is usually operated with the engine running - wire to Cranker
-If it is an accessory that is usually operated with the engine stopped - wire to Aux
For a Winch the following also applies.
-If you have no Isolator or a high current manual solenoid then it doesn't matter a terrible lot.
-If you have VSR battery isolater wiring it Cranker means the Alternator etc stays in circuit because if you wire it to Aux the voltage drop when you run the winch will usually trip the Isolator and take the Cranker and Alternator out of circuit so they no longer load share.
-If you have a DC/DC charger then you definitely want to be on the Cranker
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

As others have said, winch always on cranker. Cranker battery is a sprinter and aux a long distance runner. Sprinter = more burst current which the winch needs.

Thanks guys
It's a simple one but if you don' ask no one will tell.
Last week I also noticed discharge from near the TURBO had it checked and told pull it all out and clean! So far so good?
