Good afternoon,
This is my first post here, and I apologize its a question that brought me here to post for the first time.
But I have a bit of a problem in wiring.
I have a few trailers the main one being a car hauler, that has its own battery in a box to power lights and a badland winch.
While the trailer is connected to the truck it is currently not trickle charging the batteries. I would like it to, but for that to happen I need to be able to have it be able to disconnect the trickle charge while the winch is being used.
I know a switch is the easiest way to do this, but the trailer is used by multiple drivers, and I don't want anyone's truck blowing fuses if some one forgets to flip the switch.
What I would like to accomplish is the following, the winch is either extended or retracted with the hardwired remote.
The remote is three position switch that either gives off a positive (+) signal to the relays for either. When the remote is hit for either I would like for a relay or module to cut the trickle charge from the trailer harness.
Can anyone think of a relay set up or module where this would work?
Thanks,

A pair of diodes and a relay with normally closed contacts rated at more than the 'trickle charge' fuse. Non-banded diode leads connect to in/out control wires, one diode on each. Banded ends connect together and then to coil lead of relay. Other coil lead of relay connects to ground. Contacts of relay connect inline to trickle charge (battery positive). Diodes need to be rated for current of relay coil. The relay when activated will disconnect the charge wire.

What device is going to "trickle charge" your trailer's battery? Are you planning to connect directly to the tow vehicle DC system?

I'm guessing the trailer hookup has a 7 conductor cable. This would allow for a battery/charge connection, along with the usual lighting and trailer brake circuits.

That sounds like it could work, I'm just not very savvy with diode use. I'll look into it now. Thank you

You could use two of the above mentioned relays. More expensive of course, diodes are cheap. Wire one coil terminal of each relay to the in/out wires, other coil terminals to ground. The contacts would need to be wired in series so as to disconnect the charging power.

Good evening,
I was hoping some one could help me with the wiring on the stock 7way plug on a 2018 silverado 2500hd.
I need to know which wire is the 12v for battery trickle charge.
Thanks.

Thanks!, Only question is as I'm learning here could you direct me as to how to wire the relay and diodes?
Thanks,
