Wiring Diagrams

Use the Wiring Diagram Cross-Reference chart to

determine the wiring diagram version number for a

given model number and spec number. Then find that

version number, the controller type, and the alternator

type on the Controller Wiring Diagrams Reference chart

to determine the wiring diagram numbers for your unit.

Refer to Controller Identification for controller type

identification, if necessary. Refer to the generator set

nameplate for the alternator type. A wound field

alternator is identified with a W as the last digit.

Example: Gen. Model 4UA9W.
