Romaine Electric Corporation in Chula Vista distributes alternators, starters, and rotating-electrical components from its San Diego regional warehouse at 370 Trousdale Drive, serving automotive, truck, marine, agricultural, and military applications nationwide. The facility stocks Delco-Remy, Denso, Bosch, Hitachi, Mitsubishi Electric, and Prestolite units alongside proprietary remanufactured assemblies, supplying fleet operators and transportation companies such as Men In Black Transportation that maintain multi-vehicle electrical inventories. On-site armature rewinding, rotor balancing, and stator reconditioning extend the life of high-amperage alternators used in emergency vehicles, transit buses, and Class 8 over-the-road trucks. The industrial and agricultural division stocks 12-volt and 24-volt starters for Caterpillar, John Deere, Cummins, and Detroit Diesel engines, addressing the heavy-equipment market east of Interstate 805 in Chula Vista's Otay industrial zone. Wholesale accounts with independent repair shops and fuel stations such as G & M Oil Co keep replacement units on local shelves for same-day installation when a charging-system failure strands a vehicle. Technicians bench-test every remanufactured unit at rated load on a Regitar or Sun VAT-60 analyzer, verifying output amperage, voltage regulation, and diode-trio integrity before shipping.
