I have had this issue on several trailers. If you use the 12 volt pin in the trailer light plug to keep the batteries charged for an electric winch or a power lift tail, you can/will blow the fuse when using the winch or lift.
I have three large batteries on my trailer. One provides the power to the hydraulic dove tail. The other two power the electric winch. Using the light plug/wiring to keep the batteries charged works fine. The issue is if I leave the trailer light cord plugged into the truck when I use the hydraulic lift or the electric winch, it will blow the fuse as the small charge wire/circuit tries to carry the load. I tried a circuit breaker and it gets the wiring hot.
I have had this issue on the last three trailers I have had an electric winch on.
Is there a way to keep the batteries charged and not have to unhook the light plug when I sue the winch or lift???
I am not going to run heavy battery cable to the trailer from the truck batteries.
