Save time & money by testing the component first!

Current diagnostic routines dicatate time consuming circuit testing and NEVER test the component.

More and more of today's vehicles are using Pulse Width Modulated (PWM) motors, actuators and solenoids. You can't simply test them by directly applying 12 volts. This can cause expensive misdiagnosis. PWM Power Pro is the only tester that can adjust the output percentage from 0% –100% to effectively pinpoint the cause of the failure.

PWM Power Pro Can Drive

  • Fuel Pumps
  • EGR / EVAP Solenoids
  • HVAC Blower Motors / Blend Doors
  • Cooling Fans
  • Drive-by-Wire Actuators
  • and much more!
