GENERAL INFORMATION The Purkeys Direct™ system improves the charging of liftgate batteries by utilizing a DC/DC Converter to boost the voltage for optimal charging. The boost in voltage overcomes the normal voltage drop caused by the extended distance between the liftgate batteries and the vehicle charging system.
MOUNTING THE DIRECT CONTROLLER Step 1: Mount the Direct Controller at the front of the trailer via the mounting holes on the L-bracket. Note: If the L-bracket is not used, mount the Direct Controller at the front of the trailer via the mounting holes on the mounting plate.
