Purkeys has announced that the 20 Amp Applied Load Module comes with the Purkeys' Liftgate Double Check as a free accessory to the testing tool.

The tool gives technicians the ability to perform a load test on their vehicles. The 20 Amp Applied Load Module works in conjunction with the Liftgate Double Check to ensure that the tractor is going to have sufficient energy to charge liftgate batteries.

“The 20 Amp Applied Load Module pulls a 20-amp, fixed load and gives you the ability to check what the voltage drop is on the tractor,” said Rylar Masco, Purkeys’ national OEM representative. “Now technicians can make sure they have sufficient output voltage to the trailer.”

Too much dropped voltage means that a liftgate charging system will not function properly. Purkeys’ Direct and Select need at least 10.5 volts at the trailer to charge the liftgate batteries reliably, according to the company. The 20 Amp Applied Load Module comes equipped with an LED display that informs technicians when the system is ready to start and when the test is complete.
