Catalog description

One lecture. Three lab. Emphasizes service of automotive and light truck starting and charging systems. Topics will include: starting system diagnosis and repair, charging system diagnosis and repair. Students will be able to: perform starter current draw tests; determine necessary action; perform starter circuit voltage drop tests; determine necessary action; inspect and test starter relays and solenoids; determine necessary action; remove and install starter in a vehicle; inspect and test switches, connectors, and wires of starter control circuits; perform necessary action; differentiate between electrical and engine mechanical problems that cause a slow-crank or no-crank condition; perform charging system output test; determine necessary action; diagnose charging system for the cause of undercharge, no-charge, and overcharge conditions; inspect, adjust, or replace generator (alternator) drive belts, pulleys, and tensioners; check pulley and belt alignment; remove, inspect, and install generator (alternator); perform charging circuit voltage drop tests; determine necessary action; locate and interpret vehicle and major component identification numbers (vin, vehicle certification labels, and calibration decals).
