AT 121 - Ch 3/4 - Lab 4 - Component Measuring, Identification, and TestingName: ____________________________________Date: ____________________________________NATEF TASKS - VI. ELECTRICAL/ELECTRONIC SYSTEMSA3. Research applicable vehicle and service information, such as electrical/electronic system operation, vehicle service history, service precautions, and technical service bulletins. P-1A4. Locate and interpret vehicle and major component identification numbers (VIN, vehicle certification labels, and calibration decals).P-1A11. Check continuity and measure resistance in electrical/electronic circuits and components using an ohmmeter; determine necessaryaction. P-1A16. Inspect and test switches, connectors, relays, solenoid solid state devices, and wires of electrical/electronic circuits; perform necessary action. P-1Station 1 - Using the components provided verify if the following fuses or wires have continuity.A. OK / NOT OK B. OK / NOT OK C. OK / NOT OK D. OK / NOT OKE. OK / NOT OK F. OK / NOT OK G. OK / NOT OK H. OK / NOT OKJ. OK / NOT OK K. OK / NOT OK L. OK / NOT OK M. OK / NOT OKStation 2 - Identify the components on the board, and Draw the symbol next to the component. Measure the resistance of the component.Component 1. Name:__________________ Ohms ________________Component 2. Name:__________________ Ohms ________________Component 3.

Name:__________________ Ohms ________________1Station 3 – Relay Inspection – Use your book or notes to answer the fill in the blanks below..Write in the correct pin numbers on the standard ISO relays below.Test the following relays; describe the faults (if any). Use a 9v battery to actuate the relay, and a DVOM to test the continuity of switches, coils, and contacts… Relay coil spec is 90 Ohms.Relay A> Coil OK/Not OK Switch Contacts OK/Not OKRelay B> Coil OK/Not OK Switch Contacts OK/Not OKRelay C> Coil OK/Not OK Switch Contacts OK/Not OKRelay D> Coil OK/Not OK Switch Contacts OK/Not OKWhat is the maximum voltage and amperage these relays can transfer?____________________________________________________________________Station 4 - Measuring VoltageMeasure the open cell voltage of 3 vehicles out in the shop.OCV = Open Cell Voltage - Terminal to terminal VoltageCV = Terminal Voltage - Clamp to ClampVehicle 1 (Y/M/M) _____________________________ OCV __________________ CV ____________Vehicle 2 (Y/M/M) _____________________________ OCV __________________ CV ____________Vehicle 3 (Y/M/M) _____________________________ OCV __________________ CV ____________Was there a difference in the voltage between the two readings OCV versus CV? If so this indicates slight ________________ between the __________________ and the __________________.Are there any TSBs for these vehicles related to (main) battery or low voltage
