PROBLEMS

(SYMPTOMS)

The engine will not go to high idle when using auxiliary power. The automatic idle system functions normally when welding. Weld and auxiliary power is normal when the idle switch is in the “High Idle” position. The engine starts, runs, and shuts down normally.

POSSIBLE AREAS OF

MISADJUSTMENT(S)

OUTPUT PROBLEMS

The load applied to the auxiliary receptacles may be too low. A load of 100 Watts minimum is required for the idle system to operate reliably.

Check that any power cords are in good condition and properly connected.

Verify that any devices operating from the auxiliary AC power are operating correctly and are in good condition. Try plugging the device into another source of AC power to be sure it is functioning properly.

Some devices may test the input power for correct voltage and frequency before they will operate. If such a device is being used, the idle switch will need to be placed in the “High” position. The current drawn by many of these devices, when testing the power, is too low to reliably activate the automatic idle system.

RECOMMENDED

COURSE OF ACTION

The Toroidal Current Transformer or the wiring connecting it to the idler/engine protection PC board may be faulty. Check the resistance of the toroidal current transformer. The resistance should measure 10 to 14 Ohms.

The Idler/Engine Protection PC board may be faulty.
