    How to test the resistance of a fuel injector

    In this video, we'll show you how to use DYVO to test the resistance of a fuel injector. You can use this same method to test the resistance of almost any component. DYVO applies more power through components than a traditional multimeter in Ohms, providing more accurate results and a better indication of the component's health.

    How to test a crankshaft position sensor

    Follow along as we use DYVO to test a crankshaft position sensor (CKP) on a 2013 Dodge Dart 1.4 liter. Learn how to quickly test a 5V reference, ground, signal circuit, and control module. Use DYVO as a known good sensor to safely pull a circuit down.

  • How To Test A Battery Solenoid

    How To Test A Battery Solenoid

    In this video, we test an RV (1999 Ford Econoline) where the house battery isn't charging. Learn to test a battery isolator solenoid using DYVO. Understand the limitations of traditional battery solenoids and why it is better to use an automatic charging relay or latching solenoid (switch) such as the Blue Sea Systems m-ACR 7601. Also applicable to starter solenoids and continuous duty solenoids.

  • How to test a headlight
    • 4/19/24

    How to test a headlight

    Learn the fast way to test a headlight and know if it only needs the bulb or if there is an electrical problem using DYVO. Easy to use and more accurate than a standard multimeter or DMM.

  • How To Test A Fuse
    • 4/19/24

    How To Test A Fuse

    Learn how to quickly test fuses in a car and determine if the fuse is good or open (blown). DYVO is the best meter to test fuses. It combines a test light, voltmeter, and ohmmeter all in one!

  • How to test a fuel pump
    • 4/19/24

    How to test a fuel pump

    Learn how to quickly and easily test a fuel pump using DYVO. This video focuses on the electrical tests of a fuel pump and circuits. Test for power and ground, as well as fuel pump resistance. Not sure if you have a bad fuel pump that needs replacement or an electrical problem? Test it first and diagnose with confidence using DYVO.

  • How to test a cam actuator solenoid
    • 4/8/24

    How to test a cam actuator solenoid

    Learn to use DYVO to test a cam actuator solenoid. This is used in variable valve timing (VVT) systems. We'll cover testing the circuits to a cam actuator solenoid, testing the integrity (resistance) of the solenoid, and pulse width modulation (PWM) control.

  • How to test a temperature sensor
    • 4/8/24

    How to test a temperature sensor

    Use DYVO to test the sensor, all the circuits, and pull a circuit down to verify the control module is good.

  • How to test a SPDT aftermarket switch
    • 4/8/24

    How to test a SPDT aftermarket switch

    Using DYVO to test a rocker switch. Specifically, single pole double throw (SPDT). This switch has one input and two outputs. These switches were brand new out of the bag. Watch how to use loaded voltage drop testing to find out if the switch is good or bad.
