If you use dual-battery, ensure adequate electricity to drive the electric winch. It takes a lot of power for big electric winch, and in the case of only one battery, the use of electric winch for longer time will easily run out. Then you should install a larger generator or dual-battery system, or both installed to support the electric winch.
When using the electric winch, keep the engine running and improve the speed so that supply power for the electric power winch. If the electric winch's motor performance is very difficult or slow down (hard drag), it suggests that the battery power is running out. The electric winch should be stopped when it feels hot. Make the electric winch cool while charging for the winch battery and you can speed up the cooling process by pouring water on the electric winch.
When installing the electric winch, it is very easy to damage the airbag sensors. If you intend to install, you should be sure to understand the potential installation of airbag problems. If you plan to install the electric winch by yourself, first consult the vehicle manufacturer and the electric winch manufacturer.
