Trouble | Cause Cause | Redress |
Engine dose not start | No fuel in tank./ Air in fuel system./In sufficient speed of starter | Fill in fuel, vent fuel system. / Vent fuel system. / Charge batteries. |
Engine does not start at temperatures below 0 C | See above or the ready to start / signal lamp does not light | Of above , or change lamp. |
Defect of series resistor solenoid / valve, or flame heater plug / Paraffin precipitation of fuel | Heat up fuel Pipings, change / Filter | |
Engine starts up but stops after brief time | Fuel tank cock closed. / Dirt in primary fuel cleaner or in fuel filter. / No fuel in tank, no conveyance of fuel. | Open cock / Clean or change filter cartridge respectively / Fill in fuel , vent fuel system. of fuel. inspect correct operation pump, replace if necessary, and check safe venting of tank. |
No power and misfiring of engine | Water or dirt in fuel system. / Interruption of air supply or heavy jamming of air filter. / Air in fuel system / Fuel filter jammed. | Clean fuel tank, fill in clean fuel replace filter, and vent fuel system. / Inspect, replace if necessary or clean. / Vent fuel system / Change filter |
Starts of fuel supply missed / Defect of exhaust brake. | Reset start of fuel supply. / Inspect and repair | |
Engine emits white or bluish fumes, | Retorted and start of fuel supply | Set correct start of fuel supply |
Engine is still cold. / Mis setting of fuel injection system. | Permit engine to heat up in operation / Check start of fuel supply inspect injectors. | |
Engine emits black fumes. | Engine is overloaded. | Reset fuel injection system / consult workshop. |
Fault | Cause | Rectification | |
No voltage build - up | 1) Insufficient residual voltage. 2) Improper connection 3) Low speed 4) Faulty Winding 5) Rotating rectifier failure 6) Faulty AVR | 1) Excite the rotor using a battery. 2) Correct the connection 3) Reset the speed to the nominal. 4) Check the winding resistance and rewind if required. 5) Replace the rotating required. 6) Replace the AVR | |
Low no-load voltage | 1) Low Speed 2) Faulty Rotating rectifier 3) Faulty Winding | 1) Reset the speed to the nominal 2) Replace the rotating rectifier. 3) Check the winding resistance and rewind if required. | |
Low voltage on load | 1) Low speed at full load 2) AVR faulty 3) Faulty rotor winding 4) Over load on alternator | 1) Set the rated speed of the prime mover. 2) Change AVR 3) Check the rotor winding resistance and if faulty, rewind it. 4) Operate on specified load. | |
High voltage on load | 1) Capacitors on the load side 2) Faulty AVR setting or AVR is faulty | 1) Disconnect the PF improvement capacitors 2) Correct the setting/Replace AVR | |
Too high no-load voltage | 1) Excessive speed 2) Correct the setting Replace AVR | 1) Adjust the revolving speed Correct the setting Replace AVR | |
Fault | Cause | Rectification | |
Voltage oscillations | 1) Incorrect AVR Setting 2) Thyristor load more that specified limits 3) Insufficient engine flywheel | 1) Set the AVR stability pot 2) Reduce the Thyristor load | |
Unbalance Voltage | 1) Unbalance load 2) Loose connections 3) Stator winding faulty | 1) Correct the load 2) Tighten the loose connections 3) Check winding resistance & rewind if required. |
