LIFTGATE DOUBLE CHECK™

Product Overview

Purkeys developed the Liftgate Double Check™ to make it easy for fleets to test liftgate charging systems and ensure they are properly working. It can test liftgate charging systems on a wide variety of vehicles. It allows drivers and technicians to troubleshoot and diagnose various issues.

The Double Check comes with an LED display that shows when the system is connected to a power source and an ammeter that shows how much current the liftgate charging system is pulling. Its connections can be fit to dual pole, single pole, or 7-way cables.

All Liftgate Double Check kits come with Purkeys’ 20 amp Applied Load Module. This accessory works with the Double Check and lets technicians perform load tests on their vehicles to make sure the tractor has sufficient energy to charge the liftgate batteries.

Benefits include:

  • Easy diagnosis of liftgate charging system issues
  • Dual pole, single pole, 7-way, and light-duty vehicle connectors
  • Separate testing of tractor and trailer electrical systems
  • Measurements in voltage and amps
  • Purkeys’ 20 amp Applied Load Module accessory

What is the Liftgate Double Check (LGDC)?

The LGDC is used to test the operation of a liftgate charging system as well as test the source vehicle to ensure that both system and vehicle are operating properly.

Why was the Liftgate Double Check (LGDC) created?

The LGDC was created to help diagnose liftgate charging system problems by isolating and checking the source vehicle and liftgate charging system separately for faster diagnosis. The benefit is that the source vehicle does not have to be present to test the liftgate charging system. Any temporary 12 volt power source may be used (i.e. car, pick-up, service vehicle).

How is the Liftgate Double Check (LGDC) used to test the liftgate charging system?

The LGDC is connected to any vehicle with a functional charging system and then to the trailer, using the correct adapters provided in the kit. An LED read-out on the tool will show current flowing from the vehicle to the charging system, and an LED indicator on the LGDC shows if the source vehicle voltage is sufficient.

How is the Liftgate Double Check (LGDC) used to test the source vehicle?

The LGDC is connected to the source vehicle using the correct adapters provided in the kit. Once the vehicle is running, a multimeter can be connected to the LGDC and a 20 amp load is placed on the source vehicle circuit using the LGDC. The voltage can be noted on the multimeter and used to determine if the source vehicle is the cause of the liftgate charging system problem.

What liftgate charging systems can the Liftgate Double Check (LGDC) be used on?

The LGDC can be used on any system that uses a 20 amp DC/DC converter for charging.

Can the Liftgate Double Check (LGDC) be used to test liftgate charging systems powered by stinger and 7-way cords?

Yes, the LGDC kit contains all the necessary adapters to test liftgate charging systems powered with single and dual pole stingers as well as 7-way cords.

What vehicle can be used to power the Liftgate Double Check (LGDC) for testing liftgate charging systems?

Any vehicle can be used that has a functional charging system that is capable of providing 25 amps of current at a voltage above 13.8 volts.

Can the Liftgate Double Check (LGDC) determine if the source vehicle has a bad stinger or 7-way cord?

Yes, the LGDC can determine if a source vehicle has a bad stinger or 7-way cord by providing the necessary adapters in the kit to test the source vehicle with and without the cords. A bad test result with the cord, and a good test result without the cord, indicate the cord is bad.
