All,
As part of a new project, picked up a vehicle that was originally equipped in a time before a bunch of fancy dual battery technologies were available. 2x yellow tops now wired up in parallel with one manual disconnect switch to separate the starter bat from aux. Winch is wired to the aux, starter bat is left alone. When vehicle is parked, I was told to manually separate the batteries so they do not discharge eachother (way more of an issue when I had one heck of a crapola starter battery, an old diehard platinum).
>Starter, alt, wired to MAIN POS
>MAIN POS wired to AUX POS
>winch wired to AUX POS
>both NEG grounded together on T case
>Mystery black wire (4 ga or 2 ga) wired to AUX NEG, can't find where it goes to ( I think this is winch ground?)
In the last week I have had to either jump my starter bat or get a jump more times than I ever have... hence picked up a matching 34/78 yellow top to avoid the serious discharging.
I'm going to try and wire up one of those manual isolator keys to be easily accessible, but would it be good to include one of those solenoids the dual battery systems use? Would you have to wire up from the solenoid to ignition signal? Would like to keep it simple.
Lastly, a major concern is both theft and the winch being live while parked. I heard horror stories from Oz where anyone with the right controller could mess with a winch, potentially catastrophically. :Wow1:
I respooled the hecka long winch cable so I know at least the old yellow top was in good shape, and the other is now brand new. Any forseen problems running the same models wired up together all the time?
thanks.
