ReferenceSpecial Instruction, REHS3413, "Wiring the 9X-9591 Electrical Converter Gp (PULSE WIDTH MODULATED)"

Incorrectly wiring the 9X-9591 Electrical Converter Gp can cause the following problems:

• Prevent the engine from operating at high idle.

• Prevent the engine from operating at full load.

• Cause the engine to exhibit instability.

• Cause the engine to experience RPM fluctuation.

• Cause RPM mismatch. For example, if the customer has set the speed to 1800 RPM, the engine will only run up to 1200 RPM.

For more information on correctly wiring the 9X-9591 Electrical Converter Gp, refer to the Special Instruction that is referenced above.
