COURSE OF ACTION
If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely,
contact the Lincoln Electric Service Department for technical troubleshooting assistance before you proceed.
Call 1-888-935-3877.
CAUTION
The battery does not stay
charged.
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.
The battery may be faulty.
Recharge and test the battery.
Replace it if necessary.
The engine alternator drive belt
may be loose. Replace and/or
adjust the belt tension.
Make sure the idle switch is in
the “AUTO IDLE” position.
Make sure there is no external
load on the weld terminals or the
auxiliary power receptacles.
Disconnect the weld cables and
unplug anything that may be
connected to the auxiliary
receptacles.
Check for mechanical restrictions
in the idler solenoid linkage.
Perform the Engine Alternator
Test.
The idle solenoid linkage may be
bent or out of adjustment. Check
that the linkage moves freely and
that the plunger does not bind in
any way.
Check that the solenoid can
freely pull in and solidly seat
against its internal stop.
Perform the Engine RPM
Adjustment Test.
The idle solenoid may have
failed. Disconnect the solenoid
leads and check the resistance
of the solenoid coil.
For code 10856, the resistance
should measure about 8.8 Ohms.
For codes 11199 and 11408, the
resistance from the black lead to
the white lead should measure
about 0.4 Ohms. The resistance
from the black lead to the red
lead should be about 15 Ohms.
