A & B Auto Electric in Chula Vista has operated as a Latino-owned auto electric and smog shop on the Broadway corridor since 2005. The shop holds Bureau of Automotive Repair STAR certification for emissions testing, placing it alongside STAR-designated stations such as Star Best Smog Station that handle gross-polluter and directed-vehicle inspections. Bilingual service in English and Spanish covers starter and alternator rebuilds, full wiring-harness diagnostics, engine tune-ups, oil changes, and California smog inspections for both OBD-II and pre-OBD vehicles. Technicians use scan tools compatible with CAN-bus, J1850, and ISO 9141 protocols to isolate electrical faults in domestic, Asian, and European platforms. Brake and suspension work rounds out the mechanical menu, addressing the same under-car systems serviced by Hernandez Tire Pros further south on Broadway. Advanced diagnostics include parasitic-draw testing and charging-system load analysis using a carbon-pile tester rated to 500 amps, identifying failing diode packs and voltage-regulator circuits before they strand a vehicle.
