Which type of Battery connection Series or Parallel Connection is used for Diesel Generator?

Diesel Generator Battery Connection
Batteries can emit explosive gases.     To reduce the possibility of personal injury, always ventilate the compartment before servicing the batteries. To remove the possibility of arching, remove the negative battery cable is first and attach the negative battery last.

When using jumper cables to start the engine make sure to connect the cables in parallel Positive to positive and negative to negative. When using external electrical source to start the engine, turn the disconnect switch to the OFF position. Remove the key before attaching the jumper cables.

To avoid damage to engine parts do not connect jumper starting or battery charging cable to any fuel system or electronic component.
Battery Parallel Connection: The accompanying illustration shows a typical parallel battery connection. This arrangement doubles the cranking amperage.

Battery Series Connection:
This illustration shows a typical series battery connection. This arrangement positive to nega…

Diesel Generator starting procedure in Cold Weather

Generator Starting Procedure at Cold Weather or Winter Season

Electrical and mechanical Metering Equipment

0.Disengage the driven unit or if equipped put the transmission in neutral

1.While cranking the engine, inject metered amounts of starting fluid

2.Engine oil p-pressure must be indicated on the gauge within fifteen seconds after starting.

Warning of Cold Weather starting Aids of a Diesel Generator

One should not use volatile material for cold starting diesel generator because of the potential for an explosion.

One must keep away all flames, sparks and arcing switches from starting fluid if it is used for starting cold weather diesel generator because it is highly flammable.

Do not breathe starting fluid fumes. Starting fluid fumes can be hazardous to ones health.

One should not use excess amount of fluid for starting the diesel generator engine because huge amount of fluid damage the diesel engine.

-Spray starting fluid into the air cleaner intake while another person cranks the engine.

How one start Diesel Generator if it is shutdown about 30 days?

Starting procedure of Diesel Generator after 30 days shutdown
If one shutdown the engine for more than 30 days to make sure the engine receives the correct oil flow through the lubricating oil system by following steps

-Disconnect the electrical wire from the fuel pump solenoid.
-Rotate the crankshaft, using the starting motor, until oil pressure appears on the gauge or the warning lamp goes out.
-Connect the electrical wire to the fuel pump solenoid valve.

-Start the engine as like as normal starting procedure

Starting Procedure of a Diesel Generator

Normal Starting Procedure of a Generator
Do not depress the accelerator pedal or move the accelerator lever from the idle position while cranking the engine. This can result in engine over speed and severs damage to the engine.]

To prevent damage to the starting motor do not engage the starting motor for more than thirty seconds, wait two minutes between each attempt to start the starting motor.

Engine equipped with air starting motors require a minimum 70 psi which is recommended by manufacturer.
a.Disengage the driven unit or if equipped put the transmission in neutral. b.With the accelerator pedal or lever in the idle position turn the key switch to the ON position and wait for the wait to start lamp to go out then turn the key to the start position. c.If the engine does not start after three attempts check the fuel supply system. Absence of blue or white exhaust smoke during cranking indicates no fuel is being delivered.

The engine must have adequate oil pressure within fifteen seconds …

How can one eliminate Generator Engine Failure?

By following daily report we can eliminate most failures and emergency repairs.
The daily maintenance following conditions 1.Low lubricating oil pressure 2.Low power 3.Power increase or engine surge 4.Erratic or no accelerator control or response 5.Any warning lights flashing or staying on

6.Abnormal water or oil temperature 7.Unusual engine noise 8.Excessive engine noise 9.Excessive smoke 10.Excessive use of coolant, fuel or lubricant oil 11.Any fuel , coolant or lubricating oil leaks 12.Loose or damaged parts
13.Worn or damages belts

Daily Maintenance Procedures of a Diesel Generator

Preventive maintenance begins with day to day awareness of the engine and its system. Before starting the engine check the oil and coolant levels such as

# Leaks # Damage parts or Loose # Torn or damaged belts or worn # Engine appearance with any change # Odor of fuel

The engine must be maintained in top mechanical condition if the operator is to get optimum satisfaction from its use. The maintenance department needs daily running reports from the operator to make necessary adjustments in the time allocated. The daily running report also helps to make provisions for more extensive maintenance work as the reports indicate the necessity.
