Purkeys has developed a way to test liftgate charging systems called the Liftgate Double Check tool designed to ensure that the system is operating properly.

The LDC provides a quick way to simulate the loads of a liftgate charging system. When using the appropriate connectors, the tool can test the truck and its connecting circuits to make sure they are working properly and capable of supporting a liftgate charging system, even if a trailer is not available.

The LDC comes with an LED light display that will tell a user when they are connected to a good power source and shows how many amps the batteries are pulling. This helps determine if the system starts and operates properly.

It is designed to fit a dual-pole, single-pole or 7-way connection and comes with connectors for all of those types. There is a breaker at the top for safety and there are two inputs for multimeter leads at the bottom of the LDC.
