F G WILSON Product Lines We Repair
Our engineers are trained on the full F G WILSON product range. Below are the major product families we service.
SR4, SR5, SR6 Range (4-6 kVA to 250 kVA)
Compact to medium-duty diesel gensets used in small manufacturing units, retail chains, and backup power. Common failures include fuel injection nozzle clogging, governor hunting, and alternator voltage regulation loss due to poor fuel quality and Indian climate dust ingress.
P575, P750, P1100 Range (575 kVA to 1100 kVA)
Industrial-grade gensets for large plants, hospitals, and data centres. Frequent issues include PCB moisture ingress, fuel filter blockage from contaminated diesel, exhaust thermometer calibration drift, and automatic synchronising relay malfunction.
Automatic Transfer Switch (ATS) Panels
Static and motorised changeover switches for seamless grid-to-generator and generator-to-grid transitions. Common faults: contactor coil burnout, voltage sensing circuit failure, phase sequence detector malfunction, and relay timing miscalibration in three-phase systems.
Engine Control Module (ECM) and Alternator Regulators
Microprocessor-based governors and AVR (Automatic Voltage Regulators) managing fuel and output voltage. Typical failures: capacitor drying in Indian heat, potentiometer drift, engine speed overshooting, and zero-load voltage runaway due to load transients.
Fuel System Electronics and Injection Control
Electronic fuel injection governors and fuel pump controllers ensuring clean combustion and fuel efficiency. Defects include fuel solenoid valve stiction, injector timing sensor failures, and diesel gumming in monsoon climates causing injector blockage.

Common F G WILSON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in F G WILSON equipment arriving at our workshop.
- ✓Generator no load voltage runaway or collapse — F G Wilson AVR (Automatic Voltage Regulator) capacitors dry out in high ambient Indian temperatures (40-50°C), causing the feedback loop to lose damping. Alternator field excitation becomes unstable, output voltage oscillates between 180V and 280V on no-load condition.
- ✓Engine hunting or unstable RPM under light load — F G Wilson fuel injection governor (mechanical or electronic) loses response calibration due to contaminated diesel fuel prevalent in Indian supply chains. Carbon buildup in fuel nozzles and stiction in injector control rods cause erratic fueling, forcing the engine to hunt between set speeds.
- ✓Automatic Transfer Switch (ATS) fails to switch to generator — F G Wilson ATS contactor coil burned open due to prolonged grid fault conditions, or voltage sensing circuit fails due to moisture ingress in monsoon seasons. Phase sequence relay or under-voltage detection relay trips incorrectly, preventing generator synchronisation.
- ✓Alternator stator winding insulation breakdown or phase-to-earth fault — F G Wilson alternators exposed to humidity, salt air (coastal plants), or thermal cycling in Indian monsoon regions suffer winding insulation degradation. Moisture ingress and partial discharges eventually puncture the insulation layer between phase winding and frame.
- ✓Fuel pump controller electronic module failure or no fuel supply — F G Wilson fuel pump ECU experiences capacitor failure, transistor burnout from surge currents during grid transients, or fuel solenoid valve gets stuck closed due to diesel varnish buildup common in Indian stationary genset applications with irregular use.
- ✓Generator output frequency drift or failure to sync with grid (for parallel running) — F G Wilson speed sensor (magnetic pickup or inductive sensor) drifts or becomes intermittent, causing governor to misread engine RPM. Electronic synchronising module in ATS panel fails to maintain frequency match (50 Hz ±0.1 Hz in India), preventing stable parallel operation with grid or other gensets.

Frequently Asked Questions — F G WILSON Repairs
Do you repair F G Wilson diesel generator sets across all of India?+
Yes. Synchronics repairs the complete F G Wilson genset electrical architecture — control panels, automatic transfer switches, engine governors, AVRs, and fuel injection electronics. We offer same-day or next-day pickup from Mumbai, Delhi, Pune, Bangalore, Hyderabad, Chennai, Ahmedabad, Jaipur, Kolkata, and 100+ Indian cities. All work is completed at our Vadodara, Gujarat facility and tested to original F G Wilson specifications before return.
My F G Wilson genset voltage is unstable (jumping between 150V and 280V). What is the likely cause?+
This is a classic F G Wilson AVR (Automatic Voltage Regulator) failure, typically caused by dried-out filter capacitors in India's high-temperature environment. The excitation feedback loop loses stability, causing hunting. Synchronics diagnoses with Megger and ESR testing, replaces aged capacitors with industrial-grade units rated 105°C, and recalibrates the voltage trim. Restoration takes 2-3 days including load testing.
Can Synchronics repair F G Wilson gensets used for parallel operation with the grid or with other gensets?+
Absolutely. Synchronics specialises in F G Wilson synchronising modules, load-sharing governors, and frequency droop circuits used in parallel genset systems. We test frequency stability (±0.1 Hz @ 50 Hz), verify phase synchronisation, and tune load-sharing to ensure even kVA distribution across multiple gensets. Indian hospitals, data centres, and large plants rely on our parallel genset commissioning expertise.
What is the typical turnaround time for F G Wilson genset control panel repair at Synchronics?+
Standard repairs (capacitor replacement, relay renewal, contactor swap) take 3-5 working days. Complex faults requiring PCB rework, alternator rewinding, or ECU reprogramming take 7-10 days. Emergency rush repairs can be accommodated on request. We provide daily progress updates and photographs to customers, with final load-testing and quality sign-off before dispatch.
Do you supply spare parts for F G Wilson gensets, or only repair services?+
Synchronics primarily focuses on repair and restoration of F G Wilson equipment. However, we source genuine and reconditioned F G Wilson components including AVRs, governors, fuel injection modules, and alternator regulators for customers needing spares. We can source parts within 5-7 days for most F G Wilson genset ranges. Contact our service team for specific part inquiries and pricing.
How do I send my F G WILSON 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 F G WILSON 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 F G WILSON 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 F G WILSON 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.
