GENCOR Product Lines We Repair
Our engineers are trained on the full GENCOR product range. Below are the major product families we service.
Gencor Prime & Standby Gensets
Diesel and gas-powered generator sets ranging 10 kVA to 2500 kVA. Common repair needs include fuel injector servicing, turbocharger fouling, crankshaft bearing wear, alternator winding faults, and governor hunting. Thermal overload and fuel-system contamination are frequent in Indian industrial environments.
Gencor Industrial Alternators (SAE & Flange)
3-phase brushless alternators for gensets and motor-driven operation. Stator winding insulation failure, rotor shaft fatigue, bearing cage fracture, and AVR malfunction are typical failure modes. Indian humidity and dust ingress accelerate electrical degradation in non-encased units.
Automatic Voltage Regulators (AVR) & Governors
Electronic and electro-mechanical voltage control and speed regulation modules. Capacitor dry-out, thyristor failure, sensing coil open-circuit, and governor solenoid stiction are common failure modes. Synchronous instability and hunting behaviour often indicate calibration drift.
Automatic Transfer Switches (ATS)
Static and electro-mechanical switching systems for mains-to-genset changeover. Contact pitting, control relay chatter, sensing voltage transducer failure, and logic board corrosion are typical issues. Manual bypass operation and fail-safe testing are critical in Indian industrial retrofits.
Power Quality & Conditioning Modules
Harmonic filters, voltage stabilizers, and active load-sharing modules for multi-genset paralleling. Capacitor bank failure, filter inductor saturation, PWM controller burn-out, and current-transformer ratio errors cause power quality degradation. Indian grids with high harmonic content require expert calibration.
Control Panels & Switchgear Integration
Embedded PLC-based genset control, metering, and protection panels. Relay logic failure, current/voltage transducer drift, LCD backlight degradation, and firmware corruption are common. Integration with Indian utility protection standards (IS:6530, CEA guidelines) requires specialized expertise.

Common GENCOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GENCOR equipment arriving at our workshop.
- ✓Alternator stator winding phase-to-ground short — Moisture ingress during monsoon storage, thermal cycling stress, and manufacturing defect in slot insulation. Indian coastal and high-humidity regions see accelerated insulation breakdown in legacy Gencor units (pre-2010).
- ✓Automatic Voltage Regulator (AVR) hunting and voltage spike cycling — Thyristor commutation failure, exciter field winding open-circuit, or sensing coil transducer drift. Loose rotor damper bars and unbalanced load distribution on paralleled gensets also trigger AVR instability.
- ✓Diesel genset fuel system blockage and injector coking — Contaminated fuel storage tanks (common in Indian plants with irregular FO supply), bacterial growth in fuel tanks, and prolonged standby operation without monthly load-run maintenance. Gencor fuel pre-filters clog rapidly under these conditions.
- ✓Bearing failure and crankshaft runout/noise — Inadequate lubrication intervals, contaminated engine oil (water/fuel dilution), and worn crankshaft bearings under overload (gensets running > 80% continuous on Indian mines/mills). Manufacturing tolerance stack-up in older Gencor engines accelerates wear.
- ✓Governor solenoid stiction and speed control instability — Fuel line gum deposits on solenoid plunger, mechanical wear in governor linkage, and loss of calibration spring tension. Extended idle periods in Indian standby-mode gensets promote solenoid stiction.
- ✓Automatic Transfer Switch (ATS) contact pitting and mains-genset synchronization failure — Transient inrush currents during load transfer, inadequate DC control bus filtering, and mechanical contact wear under frequent switching. Indian power cuts (10-20 switchovers per day in rural areas) accelerate ATS contact degradation in Gencor gensets.

Frequently Asked Questions — GENCOR Repairs
Do you repair Gencor equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete Gencor genset, alternator, and control system portfolio. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all industrial cities. All repairs are performed at our fully equipped facility in Vadodara, Gujarat with load-bank testing capability up to 2500 kVA.
Can you repair Gencor gensets with burnt-out alternator windings?+
Yes. Synchronics specializes in alternator stator rewinds and rotor refurbishment for Gencor units. We perform insulation testing (megohm/partial discharge), winding pattern verification against OEM data, vacuum-pressure impregnation (VPI) for moisture resistance, and full load-bank testing at customer's ambient temperature and humidity. For critical gensets, we source factory-remanufactured stator assemblies with warranty.
What is Gencor AVR hunting and how do you fix it?+
AVR hunting is rapid voltage oscillation (hunting) — typically ±10-20V swings at 2-5 Hz frequency. It indicates thyristor commutation delay, exciter open-circuit, or sensing transducer drift in Gencor voltage regulators. Synchronics uses oscilloscope analysis to pinpoint the fault, recalibrates AVR gain and damping potentiometers, and performs variac load-sweep testing (0-100% load in 10% steps) to confirm stable voltage regulation (±2% band) across all operating points.
Do you offer extended warranty on Gencor genset repairs?+
Yes. Standard Synchronics warranty on Gencor repairs is 12 months parts + labour. For critical applications (hospitals, data centres, continuous-duty plants), we offer extended 24-month warranty plus quarterly preventive maintenance visits. We also provide spare alternator assemblies, fuel filter kits, and bearing sets on consignment at customer site for zero downtime.
Can you integrate Gencor gensets with modern SCADA and IoT monitoring?+
Yes. Synchronics retrofits legacy Gencor gensets with IoT-enabled control panels featuring real-time metering, fuel consumption tracking, and cloud dashboards. We install 4G/Wi-Fi data loggers, upgrade control relays to microcontroller-based modules, and provide mobile app access for remote monitoring. Fully compliant with Indian CEA guidelines and IS:6530 genset standards.
How do I send my GENCOR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GENCOR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on GENCOR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your GENCOR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
