R G Auto Electric & Batteries in Chula Vista has supplied automotive electrical components from 924 Broadway since 1987, operating as an authorized ACDelco parts dealer covering passenger vehicles, off-road rigs, marine engines, and industrial equipment. The parts counter stocks replacement alternators, starters, batteries, voltage regulators, and ignition components across domestic and import applications, feeding the service bays of dealerships including Chula Vista Ford and independent shops along the Broadway corridor. On-site rebuilding services include armature rewinding, rotor and stator reconditioning, brush-holder replacement, and bench testing on a dedicated alternator/starter test stand that loads units to full-output amperage before release. The marine division supplies Delco-Remy, Prestolite, and Hitachi starters and alternators for inboard and outboard applications, serving the boat traffic staging from Chula Vista Marina and the Bayfront area. Routine battery installation and charging-system diagnosis — including parasitic-draw testing with a milliamp clamp meter — complement the quick-service oil changes at Valvoline Instant Oil Change for drivers handling both jobs in a single stop. Technicians test alternator output under load using a carbon-pile tester rated to 500 amps, verifying voltage regulation between 13.8 and 14.4 volts across idle and 2,000-RPM operating ranges.
