Trailer wiring

[504]

I am finally getting around to mounting the wench on my flat bed. THe question is should I have a switch between the power(12V) and the battery? 12V is the charging circuit for the battery. 7 wire standard hookup. We never had sons but 8 grandsons are catching up with me. Grandpa can I use the trailer ,sure. It came back with a broken tail light lens,(ok) two weeks later can I use the trailer gain? Sure,this time it came back with the wires hanging from the marker lights and a single out. I have a new set of lights setting on the table right now. The last set made it a year,maybe two. I have never wired for battery charging before,just lights and brakes.

I would install an on/off switch of the size to carry the maximum current of the winch motor current draw, and fused.
When the trailer comes back needing attention, ask the driver to stay and help with repairs.

I believe the truck key turns the power wire on and off to protect the truck battery from draining.
Do you need a second on off switch
Not really but you could put one if you like as long as the switch can handle the draw

2 suggestions:
A) Run the wiring in conduit
B) Train the grandchildren

Rule we always had to follow when borrowing something. You break it, you fix it. Teaches them good life skills and they'll know how to repair something.

Are you asking whether to put a switch between 12v supply coming out of the truck to trailer battery or from a Battery on trailer to winch? OR are you trying to run winch off of the 12v coming from truck battery through 7 pin connector?
