- Test battery voltage (should be fully charged and healthy).
- Check connections and clean terminals.
- Drain, filter or replace fuel if contaminated.
- Inspect starter motor/solenoid for wear or failure.
Tip: Install a battery health-monitor and schedule start-ups regularly to avoid surprises.
2. Low or Unstable Output Voltage
🔍 What Happens
Second in Kirloskar generator issues is Generator seems to run, but voltage is too low, fluctuates, or drops under load.
✅ Common Causes
- Faulty Automatic Voltage Regulator (AVR) or alternator wear
- Improper engine speed (RPM) or load mismatch
- Internal wiring or connection issues in the alternator
🧰 How to Fix It
- Verify engine runs at correct rated speed for your model.
- Test/replace AVR fitted to your Kirloskar genset.
- Inspect slip-rings, brushes, and alternator windings for damage.
- Ensure load is within specs and that no sudden overloads occur.
Note: Always follow Kirloskar’s manual for alternator checks.
3. Overheating or High Engine Temperature
🔍 What Happens

✅ Common Causes
- Cooling system issues (low coolant, blocked radiator)
- Fan belt loose or broken
- Operating under heavy load continuously beyond specs
🧰 How to Fix It
- Check and refill coolant to correct level; inspect for leaks.
- Clean radiator fins, ensure airflow is unobstructed.
- Check and adjust fan belt tension or replace if worn.
- Reduce load or break usage into safe intervals if necessary.
Reminder: Running beyond your genset’s rating shortens lifespan.

- If faults persist, escalate to authorized technician for diagnostics.
Tip: Maintain a log of fault codes with dates for trending issues.
✅ Quick Reference Table
| Problem | Cause | Quick Fix |
|---|---|---|
| Won’t start | Battery/fuel/starter issues | Test battery, clean fuel, inspect starter |
| Low voltage | AVR/alternator or load mismatch | Replace AVR, inspect alternator |
| Overheating | Cooling system/overload | Clean radiator, check belts, reduce load |
| Excess smoke | Air/fuel/overload issues | Replace filter, check fuel quality |
| Unexpected shutdown | Oil/temp/controls fault | Check oil, read fault code, inspect wiring |
