Case Compact Tractor 2510

NOTE: On Spark Ignition engines remove the center coil wire to prevent engine from starting

Connect a volt meter (12 volt) between the positive and negative terminals of the battery

Crank the engine for 15 seconds and record voltage

Connect voltmeter (12 volt) between the starter generator 'A' terminal and ground on starter generator frame

Crank the engine and record voltage

If voltage is not the same or varies more than .5 volt, check the battery cables, clean and tighten connections

Sign off on the battery cranking voltage test

Ensure the drive belt is adjusted properly.

Disconnect all cables and wires to generator.

Connect ammeter and variable resistance in series between the 'A' terminal and generator frame.

Connect voltmeter from the 'A' terminal to the frame.

Install jumper lead from the 'F' terminal to the frame, Figure F-9.

Drive the unit at specified RPM.

Adjust to specified voltage by varying the resistance.

Is the ammeter reading lower than specified amperage?

If amperage output is too high, disconnect the jumper lead from the field 'F' terminal.

Warning: This procedure requires trained personnel with PPE!

IMPORTANT: Under no circumstances should a pry bar be used on the starter - generator to obtain belt tension, as damage to the bearings could result.

Is the belt tension correct? (The belt can be depressed 1/4\ (finger pressure) between the pulleys)"

Sign off on the belt adjustment

Warning: This procedure should be performed by trained personnel only

Volt meter reading after 15 seconds

Is the volt meter reading less than 9.5 volts?

Sign off on the battery bench load test

Warning: This procedure requires trained personnel with PPE!

Enter the specific gravity reading from the hydrometer

Enter the temperature of the solution

If the temperature is above or below 80°F, adjust the specific gravity reading by adding or subtracting .004 gravity points for every 10° difference.

Does the adjusted specific gravity reading fall within the acceptable range?

If the specific gravity readings between the cells show a variation of .025, the battery should be replaced.

Enter the battery terminal voltage while charging

If the battery terminal voltage exceeds 15.5 volts while charging, reduce the charging rate.
