  1. DIAGNOSTIC TEST TOOLS

  2. JUMPER WIRES • USED FOR TEST PURPOSES • ABOUT 6”, 12” 3 FT, AND 15 FT. • LARGE ENOUGH GAUGE • DIFFERENT TERMINAL ENDS • ALLIGATOR CLIPS

  3. TEST LIGHTS • NON POWERED LIGHT • TELLS PRESENCE OF VOLTAGE • EASY AND QUICK TO USE • LOW INTERNAL IMPEDANCE • SELF POWERED LIGHT (CONTINUITY TESTER) • WORKS LIKE OHMMETER • LOW COST

  4. DIGITAL VOLT-OHMMETER • 10 MEG OHM IMPEDANCE • DIGITAL READOUT VERY PRECISE • MULTI-METER (MULTI-USES) • DIODE TESTER • AUDIBLE CONTINUITY TESTER • OVERRANGE INDICATOR

  5. DVOM VOLTAGE TESTS • Power Switch • Polarity • Low battery • Hook across (parallel) device or circuit being tested • Adjust to most accurate range

  6. DVOM AMPERAGE TESTS • Fuse Protection • Hook in series with circuit • Function selector adjust to most accurate range • Maximum amperage of meter • NOTE: DOUBLE CHECK YOUR CONNECTIONS BEFORE YOU DO TEST. CHECK YOUR SETUP!!

  7. DVOM OHMMETER TESTS • Isolate component to be tested • fuse protected • Function selector to most accurate range • Start with highest range and turn down range until most accurate reading • Over-range indicator

  8. TEST CONNECTIONS

  9. Reading the DVOM Handout

  10. LOGIC PROBE • TELLS PRESENCE OF VOLTAGE • TELLS PRESENCE OF GROUND (LOW VOLTAGE) • WILL NOT HURT COMPUTER CIRCUITS • LIGHT AND AUDIBLE TYPE

  11. COMPUTER SCANNER • Retrieve Trouble Codes • Display Data Stream • Perform System Function Tests • Reset Instrumentation Lights • Operate Systems for Test Purposes • Adjustment of Engine Control Parameters

  12. Later Dudes!
