AIR CONDITIONER GP 1130657 - Caterpillar

Note: Use this procedure during the installation of a new variable frequency controller or during an operational test of the variable frequency controller.
Apply the parking brake and place the propel control lever in the STOP position. Stop the engine. Turn the key start switch to the ON position. Put the throttle switch in the HIGH position. Put the propel range switch in the LOW position.Note: This procedure should be performed with the key start switch in the ON position, but the engine stopped.

Disconnect the main wiring harness from the electrical connectors for the vibratory pump. Assemble the fabricated wiring harness. Refer to the illustration and the charts that are provided for specific details. Install the fabricated wiring harness in the main harness. Note: The amperage reading which is given during the procedure may be used to predetermine the vibration frequency values for the Variable Frequency - Test.Note: In order to obtain the correct readings, the nominal amperage values for the minimum frequency settings should be checked and adjusted before doing the maximum frequency settings.
