Purkeys’ tractor load tester

Purkeys 20 Amp Applied Load ModulePurkeys’ 20 Amp Applied Load Module is designed to perform load tests on trucks. The device pulls a 20-amp fixed load to help determine the tractor’s voltage drop and make sure it has sufficient output voltage to the trailer to provide enough energy to charge liftgate batteries. An LED display informs technicians when the system is ready to start and when the test is complete.
