PROBLEMS

(SYMPTOMS)

The machine will not idle down to low RPM when weld and auxiliary loads are removed.

The machine has normal weld and auxiliary output. The engine starts and shuts down normally.

(continued)

POSSIBLE AREAS OF MISADJUSTMENT(S)

OUTPUT PROBLEMS

RECOMMENDED

COURSE OF ACTION

There may be voltage in the toroidal current sensor circuit. Unplug the current sensor from the PC board. Unplug J2 for code 10856, and J32 for codes 11119 and 11408.

If the machine idles down after the sensor is unplugged, check the wiring between the PC board and toroidal current sensor for damaged insulation and electrical contact with other electrically live components. (See the wiring diagram) If the wiring is good, there is likely a load on the auxiliary circuit. Check all wiring and components in the AC auxiliary circuit. (See wiring diagram)

If the machine still will not idle down, check all wiring connected to the solenoid. See the wiring diagram. Look for damaged wiring, poor connections, dirty or corroded terminals, etc. If all of the wiring is good, replace the PC board.
