Generator Repair in Fontana
A generator has one job — start and carry load when it is needed — and it usually announces its problems at exactly that moment. Our Fontana shop repairs towable rental-fleet generators and standby sets: the diesel engines that drive them, starting and charging systems, and mechanical service that keeps a set ready instead of hopeful.

Engine-first generator service
Most generator failures we see are engine and support-system failures: fuel systems gummed from sitting, starting circuits, cooling problems, and engines worn from long rental hours. That is home turf for a shop that rebuilds diesels daily. We service the complete machine, test under load where the fault lives, and document what we find.
Light towers — the generator’s close cousin on every night job — are serviced by the same crew.
