battering wiring on horse trailer
I have a horse trailier with what I think is a 6 volt battery on the trailier to activiate the emergency electrial brakes. I just installed an electrical tongue jack wired to a 12 vdc riding lawn mower battery.
The 6v gel battery appears to be hot wired from the truck plug to provide a continuous trickle charge when hooked up.
How do I wire up the 12vdc battery to receive a trickle charge also?
